Abstract

The purpose of this book is to convey the evidence (Guyatt et al, JAMA 274(22): 1800–1804, 1995; Guyatt et al, JAMA 284(10): 1290–1296, 2000) in support of procedural dermatology therapies for specific indications. After sifting the data, chapter authors provide their assessment in words and numerical ratings. Specifically, findings based on evidence are accompanied by the level of this evidence in parentheses immediately following. At the conclusion of each chapter, a table is provided that lists findings and recommendations, with numbers to represent the associated levels of evidence and strengths of recommendation.
