期刊介绍：

Full text versions of the Cochrane reviews and protocols on developing systematic reviews are contained in the Cochrane Database of Systematic Reviews (CDSR; Cochrane Reviews). A Cochrane review combines all relevant studies concerning a therapeutical problem. The reviews are formally and structurally standardized and are usually counted among the studies of highest scientific evidence. Before its production a protocol of every Cochrane review is made which describes the topic as well as the quality criteria. The revision of a Cochrane review takes place if there are new studies dealing with a therapeutical problem or as soon as a correction is necessary. Bibliographical details, indications, descriptors as well as abstracts can be searched. Full texts are available for a fee.
