Cochrane Database of Systematic Reviews contains full text articles, as well as protocols focusing on the effects of healthcare.
The reviews are highly structured and systematic, with evidence included or excluded on the basis of explicit quality criteria, to minimize bias. Data is evidence-based medicine and is often combined statistically (with meta-analysis) to increase the power of the findings of numerous studies, each too small to produce reliable results individually.
FULL TEXT - Look for the HTML or PDF icons under or beside the abstract to view each review in full text.
PEER REVIEWED - Articles located in the Cochrane Database of Systematic Reviews are considered peer reviewed and are indexed in MEDLINE.
