THE ARTICLE BY Chen et al1 titled "A Comparison of Dermatologists' and Primary Care Providers' Accuracy in Diagnosing Melanoma: A Systematic Review" offers a wonderful example of meta-analysis based on well-defined criteria. It serves as a superbly instructive and illustrative example of how to ask a well-defined clinical question and how to plan a well-designed clinical study to answer it. Researchers in all areas and levels of clinical dermatology should examine this article and strive to incorporate the lessons it offers into their own work.
