This text is a developed and expanded successor to "Causal Relationships in Medicine: a Practical System for Critical Appraisal" Critical appraisal is now the central focus of evidence-based medicine and knowledge-based healthcare, and is currently a major influence in most countries. The book has been thoroughly revised and new sections on meta-analysis, evidence-based-medicine and misclassification have been added. The text presents a system of critical appraisal to help the reader evaluate studies in the health and medical fields. It should be of particular interest to postgraduate students in health sciences (public health and clinical research) and undergraduate medical students for whom the book can act as a methodological textbook with emphasis on critical thinking.
