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 5 topics covered by this site, largest first. Child restraint27 papersMotion sickness25 papersChild sleep travel14 papersKids screens travel11 papersDriver breaks6 papers
Where the evidence sits. The 5 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. 31241612meta-analysis (31)randomised trial (24)review (16)other (12)
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.
