Do authors of review articles use systematic methods to identify, assess and synthesize information?
Review articles are an important source of summary information for practising clinicians to assist them in remaining current with the rapidly expanding medical literature. Consequently it is essential that these be of the highest quality. In this study we evaluate, according to published criteria, the methodological quality of review articles (R) including meta-analysis (MA) appearing in a major cancer journal, Journal of Clinical Oncology (JCO), 1983-1995. ⋯ With the exception of MA, the majority of authors contributing reviews to a major cancer journal, JCO, did not use systematic methods to identify, assess and synthesize information. Initiatives such as the Cochrane Collaboration Cancer Network can support and educate clinicians who wish to perform systematic reviews, but quality of reviews would also improve if author, editors and readers systematically applied any of the sets of criteria now available in the literature.
