Ovid’s Evidence Based Medicine Reviews includes the Cochrane Library as well as ACP Journal Club. The Cochrane Library is a collection of high-quality, independent evidence to inform healthcare decision-making.
Cochrane Central Register of Controlled Trials is a bibliographic database of definitive controlled trials, and part of Ovid's EBM Reviews collection. It contains over 300,000 bibliographic references to controlled trials in health care together with references to clinical trials identified by contributors to the Cochrane Collaboration in MEDLINE and EMBASE. Contributors follow quality control standards to ensure that only reports of definite randomized controlled trials or controlled clinical trials are included. These controlled trials included were identified by the contributors to the Cochrane Collaboration to create an unbiased source of data for systematic reviews.
The Cochrane Database of Systematic Reviews is part of Ovid's EBM Reviews collection, and includes the full text of the regularly updated systematic reviews of the effects of healthcare prepared by The Cochrane Collaboration.
