The Cochrane Collaboration is a global independent not-for-profit organisation made up of a network of researchers, health professionals, patients, carers, and other people interested in health. Our network with members in more than 130 countries gathers and summarizes the best evidence from research to help you make informed choices about treatments and other health interventions, and we have been doing this for over 25 years.

We work together to produce reliable systematic reviews of the benefits and harms of healthcare interventions that are used by individuals, organisations, and governments around the world. These reviews are recognised as representing an international gold standard for high quality, trusted information.

There is no one place or office that is 'Cochrane'. Each group is a 'mini-organization' with its own funding, website, and specialized tasks. Our global network of members and supporters work together to achieve our strategic goals and are usually affiliated to one or more Cochrane Groups based on their interests, expertise, and/or geographical location.

We do not accept commercial funding for our groups or review production, and we have a strict policy regulating conflicts of interest for authors. This is vital for us to generate authoritative and reliable information, working freely, unconstrained by commercial and financial interests.
