Jeffrey Beall did publish a list of predatory journals and publishers, but has withdrawn it due to harassment.

They may lack independent editorial oversight and peer review with no supervision of content by the parent journal. Many, but not all, papers published in medical journals are primary sources for facts about the research and discoveries made. Use up-to-date evidence edit Keeping an article up-to-date while maintaining the more-important goal of reliability is important. "The Journey of Research - Levels of Evidence CAPhO". However, when it comes to actually writing a Wikipedia article, it is misleading to give a full citation for a source after reading only its abstract; the abstract necessarily presents a stripped-down version of the conclusions and omits the background. "Brandon/Hill selected list of print books for the small medical library" (PDF).

Annals of Internal Medicine.

There is no magic number, but it is useful to compare the authors to others' in the same field of study. Cooper BE, Lee WE, Goldacre BM, Sanders TA (August 2012). Such reviews typically do not contain primary research, but can make interpretations and draw conclusions from primary sources that no Wikipedia editor would be allowed. However, they normally contain introductory, background, or review sections that place their research in the context of previous work; these sections may be cited in Wikipedia with care: they are often incomplete 20 and typically less useful or reliable. A sponsored supplement need not necessarily have a COI with its medical content; for instance, public health agencies may also sponsor supplements. "Predatory open access journals in a performance-based funding model: Common journals in Beall's list and in version V of the vabb-SHW" (PDF). Obvious or overt bias in a source is a difficult problem for Wikipedia. If an editor has access to both the original source and the summary, and finds both helpful, it is good practice to cite both sources together (see: Citing medical sources for details).

Although significant-minority views are welcome in Wikipedia, such views must be presented in the context of their acceptance by experts in the field. Each engine has quirks, advantages, and disadvantages, and may not return the results that the editor needs unless used carefully. The image below attempts to clarify some internal ranking of statements from different organizations in the weight they are given on Wikipedia. "Seeking health information online: does Wikipedia matter?". "Scientists' Elusive Goal: Reproducing Study Results". Wikipedia:Biomedical information, wikipedia's articles are not meant to provide medical advice. A reason to avoid primary sources in the biomedical field especially papers reporting results of in vitro experiments is that they are often not replicable 2 3 4 and are therefore unsuitable for use in generating encyclopedic, reliable biomedical content.

Such reviews should be more reliable and accurate and less prone to bias than a narrative review. Reviews in particular give a balanced and general perspective of a topic, and are usually easier to understand.


Health technology assessments or HTA s are the gold standard when it comes to assessing evidence quality. Respect the levels of evidence: Do not reject a high-quality type of study (e.g., a meta-analysis) in favor of a source from lower levels of evidence (e.g., any primary source) because of personal objections to the inclusion criteria, references, funding. Synthesis of published material advancing a position is original research, and Wikipedia is not a venue for open research. Verified, online, aysegüll (24) Göteborg, no reviews 9, verified, online, fekir (28) Göteborg, no reviews 0, verified, online, célèste (19) Göteborg 4 review. Public Understanding of Science.

The classification scheme includes about 70 types of documents. 19 To access the full text, the editor may need to visit a medical library or ask someone at the WikiProject Resource Exchange or WikiProject Medicine's talk page to either provide an electronic copy or read the source.

Drug discovery scientists at Bayer in 2011 reported that they were able to replicate results in only 20 to 25 of the prominent studies they examined; 5 scientists from Amgen followed with a publication in 2012 showing. Primary publications describe novel research for the first time, while review articles summarize and integrate a topic of research into an overall view. It arises in part due to financial interests that compete within medicine. Personal conflicts of interest edit Further information: Wikipedia:Conflicts of interest (medicine) People most interested in improving an article may have a connection to its subject. Systematic reviews and meta-analyses of randomized controlled trials can provide strong evidence of the clinical efficacy of particular treatments in given scenarios, which may in turn be incorporated into medical guidelines or institutional position papers (ideal sources for clinical recommendations).

Controversies or uncertainties in medicine should be supported by reliable secondary sources describing the varying viewpoints. Sources for evaluating health-care media coverage include the review websites Behind the Headlines or Health News Review along with specialized academic journals, such as the Journal of Health Communication ; reviews can also appear in the American Journal of Public. "Assessing evidence quality" means editors should determine quality of the type of source and quality of the publication. "Irreproducible experimental results: causes, (mis)interpretations, and consequences". Sponsored supplements edit See also: WP:sponsored Symposia and supplements to academic journals are often (but far from always) unacceptable sources. Other sources edit Reliable sources must be strong enough to support the claim. The best evidence for treatment efficacy is mainly from meta-analyses of randomized controlled trials (RCTs).

Even in reputable medical journals, different papers are not treated as of equal value. Some systematic reviews also include a statistical meta-analysis to combine the results of several clinical trials to provide stronger quantitative evidence about how well a treatment works for a particular purpose. Primary sources should never be cited in support of a conclusion that is not clearly made by the authors ( see WP:Synthesis ). There are exceptions to these rules of thumb: History sections often cite older work Cochrane Library reviews are generally of high quality and are routinely maintained even if their initial publication dates fall outside the 5-year window.

Where in vitro and animal-model data are cited on Wikipedia, it should be clear to the reader that the data are pre-clinical, and the article text should avoid stating or implying that reported findings hold true in humans. Even when an article is one of the most useful types and recently published, it can be helpful to check the journal on doaj and other databases as well as the status and publishing track of authors if they make extraordinary claims. Finally, make readers aware of controversies that are stated in reliable sources.

The "Limits" tab can further limit the search, for example, to meta-analyses, to freely readable sources, and/or "core clinical journals". If a textbook is intended for students, it may not be as thorough as a monograph or chapter in a textbook intended for professionals or postgraduates. A well-referenced article will point to specific journal articles or specific theories proposed by specific researchers. 33 Articles in newspapers and popular magazines generally lack the context to judge experimental results.

Sourcing for all other types of content including non-medical information in medicine-articles is covered by the general guideline on identifying reliable sources. Although PubMed is a comprehensive database, many of its indexed journals restrict online access.
