We get asked this fairly regularly and due to the breadth of coverage it’s really difficult to succinctly answer.  But this image is our best attempt at capturing it:

Note our use of the evidence pyramid!

With regard PubMed (and PubMed Central) this is a bit more information:

  • All content from the top 500 journals only (based – broadly – on impact factor)
  • All the RCTs in whichever of the 5,000+ journals are in PubMed
  • All systematic reviews in whichever of the 5,000+ journals are in PubMed (Trip Pro only)
  • All peer-reviewed full-text articles from PubMed Central (Trip Pro only)

I suspect this page will be a ‘living’ document, frequently edited to improve it. So, if you have any questions please let me know – jon.brassey@tripdatabase.com
