References other than those to studies are divided into three categories:
Other references cited in the text should be listed here, including those cited in the background and methods sections. If a report of a study is cited in the text for some reason other than referring to the study (for example, because of some background or methodological information in the report), it should be listed here as well as under the relevant study.
References to other published versions of the review in a journal, textbook or the Cochrane Database of Systematic Reviews should be listed here.
RevMan5 also includes an optional subheading ‘Classification pending references’ category to facilitate organisation of references while preparing a review. Any references remaining in this category when the review is submitted are not published.
