Archie provides information about your Group's topic list, and how it relates to the scope of your Group and your reviews. Use of the topic list varies between groups. Some groups populate the list with topic areas within the scope of the Group and link the Group's reviews to these topics. This information is then published in the Cochrane Library under Browse by Topic.
For another controlled trials filter that has been created and validated for the Embase project, see the Cochrane Library help page on CENTRAL Identifying Embase RCTs and CCTs for inclusion in CENTRAL and scroll down to "Set 2: Records retrieved by the new search".
