The use of systematic reviews in clinical trials and narrative reviews in dermatology: is the best evidence being used?
Systematic reviews -the most comprehensive type of literature review-should be taken into account before a clinical trial or a narrative review on a topic is undertaken. The objective of this study was to describe the use of systematic reviews in clinical trials and narrative reviews in dermatology. ⋯ Systematic reviews are not often taken into account by the authors of clinical trials and narrative reviews and this may lead to redundant studies and publications. Authors appear to use Cochrane reviews even less than non-Cochrane reviews and are therefore ignoring one of the main sources of available evidence.
