A database of top quality, constantly updated, systematic reviews (meta-analyses) created by the Cochrane Collaboration, an international organization of groups of experts. Each of the 6000+ reviews are developed using strict methodology. The majority of reviews involve prevention and therapy; however, reviews involving diagnostic test accuracy are now being added (since 2008).
