Merger proposal - Precision medicine

It seems to make sense to merge the Precision medicine article into this one as both articles make reference to the fact that the terms are used interchangeably, albeit with some groups arguing that there are slight nuances between the terms. Many key sources (see refs in intro to this article) point out how the two phrases overlap and are used to mean the same thing and as thinking develops in this area this shared use is growing.

If both articles need to explain this link and how the topics are connected, and point out that many people use the terms interchangably, it makes sense to have the content all in one place.

Thoughts welcome.... Jpmaytum (talk) 09:53, 7 January 2016 (UTC)

I agree with this statement. I am a statistician working in this field. The highlighted text provided in the precision medicine article does not differentiate it from personalised medicine, but instead is a case for precision medicine to supersede it because the latter implies that each patient will have their individual treatment tailored to them. I have some sympathy with this viewpoint (in the UK it has been referred to as ‘stratified medicine’, nonetheless, ‘personalised medicine’ is far more commonly used in the literature, so ought to be the title of this page, and merged with ‘precision medicine’.

17:27, 26 January 2016 (UTC)

What a nonsense. Precision medicine implies the idea of causal and not just final relations between treatment and outcome. As we all know, that is desire, but not caused by the quality of treatment only. The term of precision may apply e.g. to surgery and to diagnostics, but not to a general causal or even mechanical relationship between and methodologic input and some desired outcome. The fiction (!!) of precision medicine should be fine and strictly separated from the systematics of individualised or personalised medicine.Drahtloser (talk) 12:56, 27 January 2016 (UTC)

I agree with Drahtloser , topics should be kept sepereate.-- H^akan·IST 15:01, 9 February 2016 (UTC)

The two comments above are all well and good, but can we look at this in terms of the Wikipedia merger guidelines at WP:MERGE. This makes it clear that Wikipedia is not a dictionary, but designed to guide the user through knowledge. So rather than having an abstract discussion as to the precise definitions of terms, we should recognise that people use terms interchangeably (and maybe sometimes mistakenly) so a single common article guiding people to the correct definitions may have some value. Thoughts please.

Jpmaytum (talk) 17:09, 22 February 2016 (UTC)

I fully agree with Jpmaytum. The reality is that the terms are used interchangeably, despite the nuances of linguistic separation between their literal interpretations. The point of wiki as a collection of knowledge vs. dictionary is salient. Quikfastgoninja (talk) 04:33, 24 March 2016 (UTC)

As there seems no consensus for the merge, I'm closing this now. Chiswick Chap (talk) 13:21, 7 January 2017 (UTC)

Chiswick Chap (talk · contribs), Jpmaytum (talk · contribs), HakanIST (talk · contribs), Quikfastgoninja (talk · contribs), Drahtloser (talk · contribs), any change in thoughts? I was reading this article and saw: One of those tools is “precision medicine,” a term the National Research Council, which leads the Precision Medicine Initiative with the National Institutes of Health (NIH) and other research centers, prefers over the older term, “personalized medicine,” Smartt said. Haven't dug in enough to find out if this characterization is quite accurate. We should follow the sources. UPDATE: I see this a quote from the NRC clarifying is at Precision_medicine#Relationship_to_personalized_medicine and the lead to this article says the terms tend to be used interchangeably. I think a merge would make this more maintainable / less confusing, but I suppose it's not a big deal. II | (t - c) 06:18, 2 December 2018 (UTC)

Although I have not been part of the discussion, I agree that, over time, the two topics will merge in the eyes of the reading public. "Precision medicine" is a new term to me, but it seems a practical choice to merge the articles sooner rather than later.--Quisqualis (talk) 08:25, 2 December 2018 (UTC)

We decided not to go ahead for lack of consensus. If you feel like starting a new merger discussion, go ahead (Proposing a merger) and see if you can obtain consensus. I have no view on the matter. Chiswick Chap (talk) 09:28, 2 December 2018 (UTC)

Thank you Chiswick Chap (talk · contribs), Quisqualis (talk · contribs), ImperfectlyInformed (talk · contribs) - it's clear that the world is moving towards these two terms being used so interchangably as to make no difference to most Wikipedia readers. I was rather disappointed that we didn't manage to have a discussion in terms of the Wikipedia merger guidelines at WP:MERGE. Chiswick Chap - if the best way is to propose a new merge, then that probably makes sense. Are there any guidelines about when you can repropose a merger? I'm guessing 3 years isn't unreasonable in such a fast-moving world.

copied from Theranostics article

The above definition makes no sense. The term "theranostic" is more frequently used to denote linking of a diagnostic to therapeutic. The second half of the word "nostic" is supposed to represent diagnostic but sounds more like "gnostic", a word introduced into English from Greek and meaning "having a knowledge of". Theranostic could thus mean having knowledge of therapy. Moreover "theranostic" is confusing and not understood by most people and should be deleted from the vocabulary. There is no difficulty in describing this concept without using a special term. Diagnostics used to guide therapeutics are also called “companion diagnostics”. If one has to use a single word to describe a test linked to therapy, one can use "pharmacodiagnostic", which is more appropriate and easy to understand.

Although using this term has been criticized as less than accurate, the above definition does seem to be in line with today's personalized approach to medicine, especially as it relates to cancer treatment. The stakes have never been higher to know that the drug therapy is working in real time than with cancer. Tumor responsiveness is critical to successful treatment and the term used to describe the process of making clinical treatment decisions mid-therapy in direct response to that precise therapy is theranostics.

Gleevec

I disagree that use of imatinib mesylate (the real name of Gleevec) constitutes "personalised medicine". This is targeted therapy, but that is not the same as the loaded and horrible term "personalised medicine". It would be if every CML patient had his bcr/abl checked for particular resistance mutations and assigned imatinib, nilotinib or dasatinib as per the findings. That is not the case. JFW | T@lk 16:32, 27 September 2006 (UTC)

Unfortunately, I have to disagree with the previous post. Pesonalized medicine is about the right treatment, the right prevention, the right medicine, for the right person. Gleevec is a targeted therapy, in that it only works on "the right type" of cancer. Moreover it goes directly to the heart of what personalized medicine is. It is the moleculary evaluated patient, with the molecularly evaluated disease, and the molecularly designed treatment. Case in point: Gleevec, Tarceva, Amplichip all have pathophysiology molecularly evaluated, with molecularly evaluated patients, and although sometimes the medicines are used inappropriately by uneducated physicians, the majority are used appropriately on the the "right person". Most CML in the US is evaluated for the BCR-ABL fusion gene. Perhaps not in other countries, but absolutely in the US. So it should be included here. SARM | T@lk 09:32, 08 December 2006 (UTC)

I agree with JFW. Gleevec seems a lot closer to targeted therapy than to personalized medicine. I feel the same about Herceptin's inclusion. Under SARM's rather expansive definition of personalized medicine, you'd have to include HAART protocol changes based on viral resistance tests, and antibiotic selection based on what the bacteria seemed resistant to in culture. I don't think that anything which isn't one-size-fits-all should be lumped into "personalized medicine." WhatamIdoing (talk) 16:25, 7 December 2007 (UTC)

I definitely agree with JFW and WhatamIdoing. "Personalized medicine" is more of a buzz word and marketing tool than an actual medical reality. Medical geneticist (talk) 11:43, 10 August 2008 (UTC)

'Stakeholder response'

Parts of this section feel to me like they're kinda choppy in terms of language and syntax. Also, the 'Patients' and 'Genetic Discrimination' headings seemingly disagree on whether the public seems to support genetic testing or not. Needs some clarification.

I didn't wanna edit it myself without saying something first. :-) 70.119.253.214 06:52, 3 November 2007 (UTC)

Limitations of "Personalized Medicine"

This whole article seems biased to me. To say that one can make predictive statements about an individual based on what is learned about genetic variants in large populations is a fallacy. What was learned from the sequencing of Watson and Venter? That they had risks (on the basis of genetic variants) for medical conditions they already knew they had risks for (on the basis of family history). Proponents of "Personalized medicine" -- in the context of performing predictive DNA testing in healthy individuals to determine risk -- fail to recognize that unless you know which variants are actually responsible for disease and resistance to disease within a family it is extremely problematic to assign an adjusted risk based on an individual's molecular profile.

For example, imagine that your father had high cholesterol and a heart attack. You are at increased risk for high cholesterol and heart disease, simply on the basis of your family history. So, you go to your neighborhood SNP sequencing company, fork over a pile of money, and they tell you: you have SNPs A, B, and C, so your risk of heart disease is X%. What if your father had SNPs D and E? The more useful information would be to know whether you had inherited SNPs D and E, which are the variants that are most likely to be associated with disease in your family. What if your mother actually has a protective SNP? Again, it is more useful to know the variants in your own biological context. If these private variants aren't tested for in the commercial "personalized medicine" SNP profiles, then you gain no useful information.

Also, it is completely untested whether adding "predictive" genetic information will actually change an individual's likelihood of participating in preventive measures that are already proven to improve health outcomes. In fact, it is conceivable that a result on a "predictive" genetic test could worsen compliance with interventions such as diet, exercise, and moderation with regard to alcohol/tobacco/drugs. If a person is given a "predictive" genetic test result that suggests decreased risk for high cholesterol, might they subconsciously or consciously take this as license to splurge a little, thereby worsening their health with regard to other conditions (obesity, diabetes, cancer)? If a person is given an increased risk, might they take a fatalistic attitude that nothing can be done about it?

The point is that the research hasn't been done to know whether "predictive" testing is any better than taking a good family history and recommending uniform, simple interventions -- eat better, exercise better, sleep more, drink less, smoke less(or not at all), practice safe sex, etc. It's just that "personalized medicine" is a much sexier buzz word than "family practice" or "medical genetics".Medical geneticist (talk) 12:12, 10 August 2008 (UTC)

Starting a major revision

I got too peeved about the lack of NPOV in the previous version and have started a re-write. I'm happy to incorporate any suggestions/recommendations. Medical geneticist (talk) 15:39, 20 August 2008 (UTC)

Hopeless

"Personalized medicine" is a silly new catchphrase for something that is as old as Santa's beard. It must have been invented by someone with no connection to real medicine, or how else could the inventor not have been aware that medicine has always been "personalized". Of course clinicians have in the past and will in the future exploit new diagnostic methods to further fine-tune therapy to each of their patients. Genetic methods are useful, but not unique or novel in this regard.

The stupid thing about catch phrases like these - "proteome" is another pet peeve of mine - is that people like the authors of this article, who hear them, then run off and try to make them meaningful. They aren't. A real encyclopedia would indicate as much by ignoring them or offering a very terse expansion. Reminds me of Haecker, who said about Hegel and his followers:"The secret of their success consists in the fact that everyone who is brazen enough may join in." So it is with wikipedia: Popular but hopelessly distracting. If you really want to learn and understand, avoid it. —Preceding unsigned comment added by 129.97.47.64 (talk) 21:19, 23 December 2008 (UTC)

You are absolutely correct that "Personalized medicine" is an invented term that seems to imply a radical change in the way medicine is practiced but in reality is used more often as a marketing strategy than an approach to clinical medicine. Medicine was probably much more "personalized" back in the days when doctors treated their patients in exchange for goods or services and the whole business wasn't swamped by profit margins... However, as much as you (and myself as well) may bristle at the use of the term and whether it is meaningful or not, the fact is that the term IS being used and marketed. The general public wants to know what it means and how it will benefit them, and I think that it is quite reasonable to have a detailed Wikipedia entry on the topic, since it's the first page a Google seach is going to bring up.

Clearly the article prompted a very strong response from you, but rather than just ranting about the term, please help us improve the article by brazenly (or in Wiki terms, BOLDLY) clicking the "edit this page" tab and making it better. That's what I did when I first saw the page and it sounded like someone's business school essay on the subject, where the main part of the article was about "stakeholders" and "key enablers". Look at the history and see how far the page has come. I've tried to include some of these concerns about whether "personalized medicine" is an improvement on traditional clinical medicine, and at least we're trying to present a balanced viewpoint -- see sentences 3 and 4 of the introductory paragraph. Sure, there's a lot of work to be done, but you can help; and while you're at it, the page on Theodor Haecker needs help, too! :) ---Medical geneticist (talk) 20:58, 24 December 2008 (UTC)

Thanks for the reply, but my feeling is this article is beyond repair and can be improved only by starting from scratch. My version of the article would look just like my comment, only shorter and maybe a little more venomous, and it would be rolled back from the main page in 5 minutes.

Good luck with it anyway.

Not only is the article poorly written, the references are inadequate. An important source of information, the Textbook of Personalized Medicine, published by Springer in September 2009, is not mentioned. —Preceding unsigned comment added by 195.12.43.235 (talk) 06:41, 18 October 2009 (UTC)

I'm working on Medical diagnostics, which is a recognised field that encompasses pretty much all of what is known as "personalised medicine". Would talk a merger be crazy? Ian McDonald (talk) 22:53, 16 October 2013 (UTC)

"Personalized medicine" is kind of a silly name, yes, but in its modern incarnation it refers to GWAS-driven explanations for genotype-specific variance in response to a given treatment (i.e. CYP450 variants). Like it or not, the concept is real and deserves to be explained in wiki. Quikfastgoninja (talk) 04:37, 24 March 2016 (UTC)

Epigenetics has to be included- this is revolutionizing biology at present

Modify the statement into this "However, large cohort studies do not take into account the genetic and epigenetic variability of individuals within a population". In response to your statements above: I don't think this (personalized medicine) is silly- if we are after an excellent individual biological in toto care for anyone personalized medicine is the best approach.. what else? —Preceding unsigned comment added by 216.66.59.41 (talk) 03:53, 14 May 2010 (UTC)

Personalized Medicine Scandal

At a minimum, a review of the current scandal involving Dr. Anil Potti and associates should be included.

The Potti papers cited as "Further Reading" and associated work are currently under review.

Update: Dec 1, 2010

Anil Potti has resigned his position at Duke.

Collaborator Joseph Nevins has started proceedings to retract the paper

1. Potti et al. (2006), Genomic Signatures to Guide the Use of Chemotherapeutics, Nature Medicine 12: 1294.

The paper (Potti as last author)

1. Hsu et al. (2007), Pharmacogenomic Strategies Provide a Rational Approach to the Treatment of Cisplatin-Resistant Patients With Advanced Cancer, JCO Vol 25 No. 28 Oct 1, 2007

is now marked "This article was retracted on November 16, 2010".

There is a common thread in the style of statistical analysis performed in all the "personalized medicine" papers issuing from this group. First, all of the available data is pooled together, and some analysis performed on the entire set of data. This is typically a singular value decomposition, a factor analysis or something similar, and yields a handful of predictor variables. These were called "supergenes" or "metagenes" in earlier papers from this group. Then the data is split into subgroups, with further model building performed on one of the subgroups, including use of the predictors developed on the entire data set. The authors then show that the models developed on one of the subgroups continues to perform well on the other subgroups. These "validation" analyses have been called cross-validation, or split-sample training-validation analyses. From a statistical point of view, these exercises are not true cross-validation exercises, because they always use predictors developed initially on the entire data set. Really what the group is doing is overfitting a model to the entire data set, then showing that the model works well on subsets of the data. This is a known statistical phenomenon, which is why techniques such as cross-validation or split-sample evaluation were devised in the first place. Many of the papers from this group will have to be re-examined going forward, as the excessive claims of accuracy are based on overfitted models to the entire data set. Indeed when Baggerly and Coombes ran the Duke group's software on half of the data in the paper cited above (and related papers) and then truly ran a validation exercise on the other half of the data, the model's predictive ability was severely reduced relative to the claims made by the Duke group. —Preceding unsigned comment added by 142.103.207.10 (talk) 02:25, 2 December 2010 (UTC)

This article is antiquated

Are you writing the history of personalized medicine and comparing it with "aristotle"? It seems that there is nothing new about personalized medicine. You are not including the new publications that talks about let us say the importance of environment to personalized medicine (2010) and other new findings. What are you talking here are the 2001 publication , the 2007 alternative name.. what is this? I think only .00001% of the editors here know what PM is all about.

A comment on stratified medicine

It is impossible to group people having singular/common need for one treatment(in this case breast cancer for a common blah blah) because they have other genes that may interact unfavorably/ differently to this similar treatment. Even applying SM to siblings/or to a family because their genes are more or less having a high percentage of similarities I can still see that SM will fail because even in families as well as among siblings there are genes/ epigenes that will not allow a similar cure of having a similar intensity (of curing) with that of the other siblings-- in other words there is still the difference-- so I would suggest not to use SM or BlockM - for each one needs a PM type of cure- an individualized medical care not a group care like SM or BM... these 2 are impossible and are even deviating from PM... misleading PM —Preceding unsigned comment added by 69.22.174.172 (talk) 17:11, 29 April 2011 (UTC)

Useful references for anyone working on this

Hi,

I'm coming across quite a few relevant things during my work on Molecular diagnostics. The two overlap in that all the real world examples of PM are either tests or therapies; and all the tests are also examples of Molecular diagnostics. So more cross-linking?

I've come across some general articles on PM, should they be of use:

This article is a useful primer, and reaction to the first ten years of full genome sequencing:

new content about "expsome" etc

Creators of the exposome article and some related pages have added the following, which I deleted with the stated reason "revet addition that promotes one lab's publications. exposome is currently not medicine, but rather a research paradigm. is not "background"" The original poster restored it without an edit note. I reverted and re-deleted, citing WP:BRD, and just now User:So26 undeleted, again without an edit note. Not good wikipedia communication. Since the OP refused to start a discussion, I am doing it. Here is the new content.

Beyond germline genetics, molecular pathology is a much wider open area for therapeutic and preventive applications. Inter-personal difference of molecular pathology is diverse, so as inter-personal difference in the exposome, which influence disease processes through the interactome within the tissue microenvironment, differentially from person to person. As the theoretical basis of personalized medicine, the "unique disease principle"(ref)Ogino S, Lochhead P, Chan AT, Nishihara R, Cho E, Wolpin BM, Meyerhardt AJ, Meissner A, Schernhammer ES, Fuchs CS, Giovannucci E. Molecular pathological epidemiology of epigenetics: emerging integrative science to analyze environment, host, and disease. Mod Pathol 2013;26:465-484.(ref/) (which was first described in neoplastic diseases as the unique tumor principle(ref)Ogino S, Fuchs CS, Giovannucci E. How many molecular subtypes? Implications of the unique tumor principle in personalized medicine. Expert Rev Mol Diagn 2012; 12: 621-628.(ref/)) emerged to embrace the ubiquitous phenomenon of heterogeneity of disease etiology and pathogenesis. As the exposome is a common concept of epidemiology, personalized medicine is intertwined with molecular pathological epidemiology (MPE). MPE research is capable of identifying potential biomarkers for personalized precision medicine.(ref)Ogino S, Lochhead P, Giovannucci E, Meyerhardt JA, Fuchs CS, Chan AT. Discovery of colorectal cancer PIK3CA mutation as potential predictive biomarker: power and promise of molecular pathological epidemiology. Oncogene advance online publication 24 June 2013; doi: 10.1038/onc.2013.244(/ref)

This is pretty clear self-promotion by Ogino et al. Also it is not "background" for personalized medicine. The paradigm described above is an emerging one; pioneers in the field are building the basic science and infrastructure. If anything it is "forward looking research" or the like. but mostly, the fact that all the papers cited are from one group calls into question whether this is really notable enough for inclusion at all. if it stays it needs to be copyedited for better english and the claims toned down (it is not the theoretical basis for personalized medicine) and the over-wikilinking cut down.

Genotyping Definition

"Genotyping is the process of obtaining an individual’s DNA sequence by using biological assays.[10]"

I am just pointing this out, but this definition of genotyping is not quite right/misrepresentative. Genotyping is not quite the same as DNA sequencing. Genotyping is the process of confirming small snippets of DNA sequence (most commonly only one nucleotide, as in SNP genotyping, which is by far the most common type of genotyping and the most relevant to Personalized Medicine) to a known reference.

DNA sequencing is a method that can be used to perform genotyping, but today it is currently the least common method used to perform genotyping. From my experience in the industry, PCR-based and probe-based methods currently dominate the market (which is not sequencing). The notion that 23andme sequences the genome of its clients is a misleading, because their technology is probe-based. There is quite a substantial difference between DNA sequencing all 6 billion basepairs of the human genome versus genotyping 100,000 SNP sites throughout the genome.

I'm sorry if I'm being particularly technical, but as a scientist who deals in this field quite frequently, this particular section seemed to be the most glaring error in this article. Also the citation that was placed on this particular line is irrelevant/does not support the claim made. 98.110.225.95 (talk) 16:09, 5 July 2015 (UTC)

Disagree. Whether checking SNPs or longer stretches, any DNA reads are genotyping. Quikfastgoninja (talk) 14:37, 7 April 2016 (UTC)

This article should be started anew

I am a Norwegian medical doctor, specialist in neurology, currently preparing a lecture on Personalized medicine as part of my PhD thesis defence. I came to this article to gain a quick overview. As it stands now, I deem it hopelessly biased and substandard. I'm sorry, but I don't think "editing" it would be of any help. There are too many issues with this article. I once faced the same situation on another topic, one that had not been worked on by professionals before me, and the only solution I could find was to scrap the entire article and start anew. I'm not sufficiently competent on the topic of personalized medicine to do this myself, but I would appeal to geneticists to take upon themselves this effort.

Contributors to this page should be aware that "personalized medicine" is a very complex issue. Firstly, the branding of PM may create the faulty impression that this is something radically new. It is not, rather, it is an age-old feature of "good medical practice". What's new about PM is the heavy involvement of genomics and other high-tec (but also high-cost, and highly commercial) investigations that are supposed to guide treatment. In some (even many) cases they do. But generally, there is still a gap between what one could wish (and even realistically hope) that PM can achieve, and what has actually been achieved so far. By reading truly scientific articles regarding PM in the field of neurology, there is mostly depictions of what can feasibly be foreseen - very few descriptions of what has actually been achieved. However, I acknowledge that in the field of oncology, genomic-based PM is probably far more established, and plays a major role even now. As for the field of pharmacogenomics, this Wiki article states, without any caution, that knowing your genotype may help guide the treatment most effective for you. That assertion lacks a solid foundation in research - it's a hope, surely, but so far with rather little clinical value. Even though this may change (even soon), this is part of what makes this article look like an advertisment.

Given the very strong commercial interests involved in PM, and the pressure upon lay persons to have their genes checked with commercial firms, I do think that the Wiki moderators ought to be very critical towards articles like this one. Lay people may come here in order to "check out" whether PM is useful for them. They ought to be informed that the usefulness of genomic PM - in particular the direct-to-customor version of it - is strongly disputed, and by many professionals regarded as pure marketing. I realize that there may be different opinions on this issue - strong opinions going against mine. That is all right - but this article should then reflect that there is such a controversy. Usually, that means that the article should be very narrowed down, omitting strong assertions either way. The discussion on the usefulness of PM should not take place through Wiki-battles with endless textual changes and re-changes. Please erase this article, and please, someone take the time to make a more neutral version. Morten Horn (talk) 19:13, 7 January 2016 (UTC)

While I have no problem with scrapping the article and starting anew, I do think it's a bit of a stretch to say that pharmacogenomics is only "a hope" that "locks a solid foundation." Drug metabolism by CYP450 genotype? Propensity for cardiac arrhythmia based on hERG (Kv11.1) channel mutations? These are very real and present concerns.

Not broad enough

Should personalized medicine be more than genetics? It should also include other measures such as imaging techniques and proteomics. The article should move its focus from genomics but look at a broader field. Kairui jiang (talk) 18:26, 30 July 2020 (UTC) Hello,

My team has just made some edits in the sandbox: https://en.wikipedia.org/wiki/User:Kairui_jiang/Personalized_Medicine. Please take a moment to review. We will move it go live tomorrow. It is part of our class group project. Kairui jiang (talk) 18:31, 3 August 2020 (UTC)

Merge proposal

Support the July proposal to merge Precision medicine with Personalized medicine on the grounds that these are synonyms, often used interchangeably. The evidence for distinct use is weak, and seems to reflect only speculation about potential misinterpretation. So, I suggest that Personalized medicine is the better target as the more establish term, older article and more developed article. Any differences in use of the term can be discussed on the page.

• Support as well. Perhaps we can have a paragraph describing certain nuances that some groups may use, but by and large it looks like the terms are interchangeable.Citing (talk) 23:07, 27 December 2021 (UTC)

Inappropriate section blanking

16:14, 23 April 2024 a user blanks the section “External links” with an edit summary: “low-quality links; WP:ELNO”. Most of the links removed are links to government sites. I don’t think our policies allow blanking and removal of a whole section with a vague and potentially misleading edit summary like that. Please read Blanking/Removal_of_content, WP:PRESERVE, WP:NOBLANKING, WP:ELYES #3 and WP:ELMAYBE #4. Section blanking maybe considered vandalism. I have restored the removed section. Thanks. --Dustfreeworld (talk) 18:44, 24 April 2024 (UTC)

Read the first item of WP:ELNO - if a link cannot be used as a reference in the article, then it has low value unless it stands on its own as uniquely informative outside of what the article states. ELs should be used to provide unique general information.

1) If the first link to NIEHS has true relevance, it should have a sentence in the article and be referenced, but this link is just part of a newsletter and has little substance. A WP:BMI review would be needed concerning exposures and personalized medicine; 2) the second link is a 6 year old media release, and has little significance to the article and would not be a worthy reference by itself; 3) the third link only points to a journal, having no use to the general user and not worthy of supporting any statement in the article; 4) the fourth link is another 6 year old source that the general reader is unlikely to read.

ELNO: a link "should not merely repeat information that is already or should be in the article", i.e., it should expand information for the general user, be easy to read as a unique extension of the article, and be cited in the article if warranted. None of these links qualifies. Zefr (talk) 20:08, 24 April 2024 (UTC)

I don’t agree with your interpretation of WP:ELNO. Read the first item of WP:ELNO, IMO, all the sites *do* “provide a unique resource beyond what the article would contain if it became a featured article.” Further,

• 1) Per WP:ELMAYBE #4 Sites that fail to meet criteria for reliable sources yet still contain information about the subject of the article from knowledgeable sources. We don’t need RS for External links. I don’t know why you said “A WP:BMI review would be needed”
• 2) I don’t think the External links section has any time requirements as WP:MEDDATE; “has little significance to the article”. It’s your personal opinion.
• 3) You said “the third link only points to a journal, having no use to the general user”. Per WP:ELMAYBE #3, it’s A well-chosen link to a directory. And again, per WP:ELMAYBE #4, external links no need to be worthy of supporting any statement in the article
• 4) Again, External links section has *no* WP:MEDDATE requirements; “the general reader is unlikely to read.” This is your personal opinion again.

All of the links qualifies. Please don’t use the MEDRS criteria for the External links section. Thanks. --Dustfreeworld (talk) 20:59, 24 April 2024 (UTC)

Regarding 1), please pay attention - by using a minor newsletter link, you're suggesting environmental factors are relevant to PM prescription. If the topic is justified to be an EL, the first priority is to bring it into the article with a current BMI review.

Other editors can pass judgment on the low quality of the existing external links.

Also, stay cool and stop shouting on talk pages by using bold and highlighting, WP:YELL. The message is not changed by use of excessive emphasis. Zefr (talk) 22:05, 24 April 2024 (UTC)

Per the link you cite: “ALL CAPS and enlarged fonts may be considered shouting and are rarely appropriate. Bolding may be used to highlight key words or phrases but should be used judiciously. Italics are often used for emphasis or clarity but should be avoided for long passages.”

I did not use “all caps and enlarged fonts”, i.e. not shouting. I did use bolding judiciously. I didn’t use italics for long passages. Those were used to aid reading and understanding. Please stay cool, comment on content only and stop commenting on other editors. Thanks. --Dustfreeworld (talk) 22:25, 24 April 2024 (UTC)
