The Database of Abstracts of Reviews of Effects (DARE) is the only database to contain abstracts of systematic reviews that have been quality-assessed. Each abstract includes a summary of the review together with a critical commentary about the overall quality. DARE is a key resource can be used for answering questions about the effects of specific interventions, whether such questions arise from practice or when making policy. DARE covers a broad range of health related interventions and thousands of abstracts of reviews in fields as diverse as diagnostic tests, public health, health promotion, pharmacology, surgery, psychology, and the organization and delivery of health care. DARE complements the CDSR by quality-assessing and summarizing reviews that have not yet been carried out by The Cochrane Collaboration.
