The Cochrane Collaboration is an organisation dedicated to making up-to-date accurate information about the effects of healthcare readily available worldwide. It produces and disseminates systematic reviews of healthcare interventions and promotes the search for evidence in the form of clinical trials and other studies of interventions. Its main output is the Cochrane Library, which includes a database of systematic reviews, a database of abstracts or reviews of effects, the central register of controlled trials (bibliographic information on controlled trials including reports published in conference proceedings), a database of methodology reviews, and a bibliography of articles and books on reviewing research
