This text is divided into two parts, the first provides a basic introduction to the principles underlying critical appraisal and details the process of appraisal, identifying the types of questions to be asked of each paper. The second part consists of checklists, each annotated with explanatory text, designed to accompany researchers on library visits and help them make sense of the overwhelming mass of medical literature. Chapters include identifying research methods, interpreting results, appraising surveys, cohort studies, clinical trials, case control studies and review studies.
