The evidence base

What this site is built on, topic by topic: how many papers, how many are trials, and how recent. Generated from the harvest, so it cannot drift from the citations themselves.

Publications per topic A bar chart of the number of publications held on each of the 6 topics covered by this site, largest first. Inflammatory bowel disease quality of life16 papersInflammatory bowel disease biologics14 papersInflammatory bowel disease diagnosis12 papersInflammatory bowel disease diet12 papersInflammatory bowel disease trigger foods12 papersInflammatory bowel disease epidemiology10 papers
Where the evidence sits. The 6 topics below are not equally well studied, and the gap between the largest and smallest is usually the most useful thing on this page. Source: this site’s own citation harvest from PubMed and Crossref.
What the evidence base is made of A stacked bar showing the proportion of syntheses, randomised trials, cohort studies, reviews and other publication types across the whole corpus. 45129meta-analysis (45)randomised trial (12)review (9)other (2)
Study type matters more than volume. A hundred observational papers and five randomised trials support very different claims, so the mix is worth reading before the counts. Source: publication types as recorded by PubMed.
