The Cochrane Collaboration is an international, independent, not-for-profit organisation of over 28,000 contributors from more than 100 countries, dedicated to making up-to-date, accurate information about the effects of health care readily available worldwide.
We are world leaders in evidence-based health care
Our contributors work together to produce systematic reviews of healthcare interventions, known as Cochrane Reviews, which are published online in The Cochrane Library. Cochrane Reviews are intended to help providers, practitioners and patients make informed decisions about health care, and are the most comprehensive, reliable and relevant source of evidence on which to base these decisions.
