This chapter discusses the role of critical appraisal as an integral part of evidence based practice. There is no gold standard for conducting critical appraisal of medical literature. Standard check lists are presented for the specific study designs (randomized controlled trials, cohort studies, case control studies and cross-sectional studies). The check lists include questions which capture four main components of a scientific paper (introduction, methods, results and discussion), and are organized as screening questions (1. Does the research address a clearly focused question?, and 2. Was the type of study appropriate?) and detailed questions focusing on the different aspects of internal and external validity.
