What are Cochrane Reviews?
Cochrane Reviews are systematic reviews of research in healthcare and health policy that are published in the Cochrane Database of Systematic Reviews. There are five types of Cochrane Review: Intervention reviews assess the benefits and harms of interventions used in healthcare and health policy.
A systematic review attempts to identify, appraise and synthesize all the empirical evidence that meets pre-specified eligibility criteria to answer a given research question. Researchers conducting systematic reviews use explicit methods aimed at minimizing bias, in order to produce more reliable findings that can be used to inform decision making.
Cochrane is a British non-profit, non-governmental organization formed to organize medical research findings so as to facilitate evidence-based choices about health interventions faced by health professionals, patients, and policy makers. Cochrane has more than 37,000 volunteers in more than 130 countries.
The group conducts systematic reviews of randomized controlled trials of health-care interventions and diagnostic tests and publishes them in The Cochrane Library. A few reviews, in occupational health for example, incorporate results from non-randomized, observational studies.
