GI epidemiology

Sinopse

"This book covers both key methodological issues and the most important information in the field, disease by disease. It focuses on population-based information and studies looking at principles and approaches to diagnosis and treatment of diseases. GI Epidemiology brings together world authorities in multiple disciplines for the very first time, to create one clear and comprehensive source. The bulk of the chapters are divided into two parts, covering methodological issues and the epidemiology of specific GI diseases. Each chapter begins with a list of key points, followed by a review written in a clear and simple style. The methodologic chapters cover evidence-based medicine, meta-analysis, systematic reviews, genetic and molecular epidemiology, clinical trials, questionnaire design, and health economics. The disease-specific chapters note the current gaps in knowledge and suggest areas for further study."--Publisher description.
