(Note: You need to be a registered CSUEB student, faculty or staff member to access this database online.)

“CENTRAL is the Cochrane Collaboration’s register of controlled trials. The register provides bibliographic information (i.e. abstracts rather than full-text) on over 415,000 reports of trials identified by contributors to the Cochrane Collaboration. CENTRAL provides individual reviewers with easy and reliable access to the maximum possible number of trials relevant to their review topic. Trials are identified from multiple sources, including searches of bibliographic databases, handsearches of many hundreds of journals and conference proceedings, and searches of other trial registers. Since the overriding aim is to create an unbiased source of data for systematic reviews, all known controlled trials are included in CENTRAL irrespective of language of publication or where and when the studies were conducted.”
