The Cochrane Library is a collection of databases, including: Cochrane Database of Systematic Reviews (CDSR): includes all Cochrane Reviews (and protocols) prepared by Cochrane Review Groups. Each Cochrane Review is a peer-reviewed systematic review that has been prepared and supervised by a Cochrane Review Group (editorial team), according to the Cochrane Handbook for Systematic Reviews of Interventions or Cochrane Handbook for Diagnostic Test Accuracy Reviews. CDSR also includes Editorials and Supplements. Cochrane Central Register of Controlled Trials (CENTRAL): is a highly concentrated source of reports of randomized and quasi-randomized controlled trials. In addition to bibliographic details (author, title, source, year, etc) CENTRAL records often include an abstract (a summary of the article). They do not contain the full text of the article. CENTRAL is published monthly. Cochrane Clinical Answers (CCAs) provide a readable, digestible, clinically-focused entry point to rigorous research from Cochrane Reviews. They are designed to be actionable and to inform point-of-care decision-making. Each CCA contains a clinical question, a short answer, and data for the outcomes from the Cochrane Review deemed most relevant to practising healthcare professionals, our target audience. The evidence is displayed in a user-friendly tabulated format that includes narratives, data, and links to graphics. Cochrane Clinical Answers were developed by Cochrane Innovations and Wiley.
