Biometrics in dermatology is an essential tool where data evaluation results in valid interpretations. This book will be the first in this area. One part of the book will describe principal aspects of dermatological research focussing on practical advice. A special part will cover applied biometrics to provide the clinician and researcher with state-of-the-art guidelines to assess the severity of common skin diseases. An additional aspect that will be of interest to pharmacologists addresses pharmacologic assays.
