Cochrane Review Groups (CRGs) support Cochrane’s primary organizational function: the preparation and maintenance of systematic reviews. There are more than 50 CRGs, based in research institutions worldwide, each focused on a specific topic of health research.
Cochrane Centres act as a regional focus for Cochrane activities within a defined geographical or linguistic area. Their primary roles are to support Cochrane contributors in their area, and to act as a point of contact between Cochrane and their regional health communities.
Cochrane Fields focus on dimensions of health care other than a condition or topic - including the setting of care (primary care), the type of consumer (children, older people), or the type of provider (nursing). More info on Cochrane Fields is available on the Community site.
Cochrane Methods Groups provide policy advice and space for discussion on the development and implementation of methods used in the preparation of Cochrane Reviews.
