As an avid proponent of evidence-based medicine, I read with great interest the recent article by Leventhal et al.1 I laud the efforts of the authors for their diligent work in compiling much of the existing literature on this topic. However, I disagree with the authors in their methods, interpretation of the results, and the appropriateness of using meta-analysis for this group of studies.
