Evaluation of the Merits and Limitations of Evidence-Based Medicine

To the Editor Although we appreciate the efforts of Pournamdari et al¹ to highlight areas of overuse in the field of dermatology, we were greatly surprised that 2 of the selected topics were reexcision of (severely) dysplastic nevi (DN) and sentinel lymph node (SLN) biopsy for cutaneous melanoma, given the limited data supporting their conclusions. Instead of a comprehensive literature review on a specific topic, the authors chose 10 articles on 6 distinct topics, drawing conclusions without the context of other existing literature. The authors gave only 1 of the 10 studies an A for quality of evidence; 5 were rated B, and 4 were rated C.¹
