Our Take

The Cochrane Library is where evidence-based medicine lives — its systematic reviews are the field’s gold standard for methodological rigor, and CENTRAL is the most comprehensive registry of controlled trials anywhere, which makes it indispensable when building or checking a review. The trade-offs are that reviews are narrow by design (one question, done thoroughly) and can lag the newest primary studies, and full access depends on national licensing. Use it to find the definitive review on a clinical question and to harvest trials; go to PubMed or Embase for the latest primary research.

Power Tips

  • Search CENTRAL to harvest controlled trials for your own review — it is the most complete trial registry.
  • Check whether your country has free national access before assuming a paywall.
  • Read the summary-of-findings table and GRADE ratings, not just the abstract.
