Summary Guides

These short, plain-language guides — tailored to clinicians, consumers, or policymakers — summarize research reviews' findings on the benefits and harms of different treatment options. Consumer guides provide useful background on health conditions. Clinician and policymaker guides rate the strength of evidence behind a report's conclusions. The guides on medications also contain basic wholesale price information. Some guides are also available in Spanish. Reports are listed starting with the most recent.




Research Reviews

These comprehensive reports draw on completed scientific studies to make head-to-head comparisons of different health care interventions. They also show where more research is needed. There are three types of research reviews: (1) Comparative effectiveness reviews outline the effectiveness — or benefits and harms — of treatment options, (2) Technical briefs explain what is known — and what is not known — about new or emerging health care tests or treatments. Final reports are listed below by health condition, and (3) Future research needs papers are intended to be used by researchers and funders of research to help improve the body of comparative effectiveness evidence that would be useful for decision-makers.
