In the current era of evidence-based medicine, clinical epidemiology is increasingly recognized as an essential tool in the critical appraisal of available evidence and the design of new studies. Clinical Epidemiology: Principles, Methods, and Applications for Clinical Research is a comprehensive resource that introduces the reader to the basics of clinical epidemiology and explores the principles and methods that can be used to obtain quantitative evidence on the effects of interventions and on the diagnosis, etiology, and prognosis of disease. The everyday challenges of clinical research and the quantitative knowledge required to practice medicine are also examined, making this book a valuable reference for both graduate and undergraduate students in medicine and related disciplines, as well as for professionals involved in the design and conduct of clinical research.
