The Cochrane Collaboration

The Cochrane Collaboration, established in 1993, is an international network of more than 28,000 dedicated people from over 100 countries. We work together to help health care providers, policy-makers, patients, their advocates and carers, make well-informed decisions about health care, based on the best available research evidence, by preparing, updating and promoting the accessibility of Cochrane Reviews – over 5,000 so far, published online in The Cochrane Library. Our work is internationally recognised as the benchmark for high quality information about the effectiveness of health care.
