Cochrane Controlled Trials Register is a bibliography of controlled trials identified by contributors to the Cochrane Collaboration and others, as part of an international effort to hand search the world's journals and create an unbiased source of data for systematic reviews.
Cochrane Database of Systematic Reviews contains full text articles, as well as protocols focusing on the effects of healthcare. 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.
The Cochrane Methodology Register (CMR) is a bibliography of publications which report on methods used in the conduct of controlled trials. It includes journal articles, books and conference proceedings; these articles are taken from the MEDLINE database and from hand searches. The database contains studies of methods used in reviews and more general methodological studies which could be relevant to anyone preparing systematic reviews. CMR records contain the title of the article, information on where it was published (bibliographic details), and in some cases, a summary of the article. CMR is produced by the UK Cochrane Centre, on behalf of the Cochrane Methodology Review Group.
Geographical encyclopedia of names, descriptions, and characteristics of places in the world. Entries include: demography; physical geography; political boundaries; industry, trade, and service activities; agriculture; cultural, historical, and archeological points of interest; transportation lines; longitude, latitude, and elevations; distance to relevant places; pronunciations; official local government place-names and changed or variant names and spellings.
Database of Abstracts of Reviews of Effects (DARE) includes abstracts of published systematic reviews on the effects of health care from around the world, which have been critically analyzed according to a high standard of criteria. This database provides access to quality reviews in subjects for which a Cochrane review may not yet exist.
