|Cochrane Database of Systematic Reviews Included in MEDLINE®
he National Library of Medicine (NLM) has been indexing the Cochrane Database of Systematic Reviews (Cochrane Reviews) for MEDLINE since Summer 2000. As described on the Cochrane Collaboration Web site at http://www.cochranelibrary.com/ the "Cochrane Reviews are full text articles reviewing the effects of healthcare. The reviews are highly structured and systematic, with evidence included or excluded on the basis of explicit quality criteria, to minimise bias. Data are often combined statistically (with meta-analysis) to increase the power of the findings of numerous studies, each too small to produce reliable results individually."
If a Cochrane Review article is substantively updated in a later issue, NLM will create a new bibliographic citation for the updated review. The citations for the original review article and the updated review article are linked via the Update in and Update of fields which are part of the Comments/Corrections family of fields.
In PubMed, the Update in and Update of fields display as links on the Abstract and Citation formats. These links take you directly to the other record in PubMed, making it easy to move between associated citations. The fields also display on the MEDLINE format, although not as links. The Update in link will eventually display on the Summary format. See Figure 1 and Figure 2 for examples of Update in and Update of links, respectively, in the Abstract format. Please see the article, PubMed/MEDLINE Available with 2002 MeSH and Two Changes. NLM Tech Bull. 2002 Jan-Feb;(324):e2, for more information on Comments/Corrections.
