Translational Gastroenterology covers the principles of evidence-based medicine and applies these principles to the design of translational investigations. Readers will learn important concepts, including case-control study, prospective cohort study, randomized trials, and reliability study. Medical researchers will benefit from greater confidence in their ability to initiate and execute their own investigations, avoid common pitfalls in gastroenterology, and know what is needed in collaboration. Further, this title is an indispensable tool in grant writing and funding efforts. The practical, straightforward approach helps the aspiring investigator navigate challenging considerations in study design and implementation.

The book provides valuable discussions of the critical appraisal of published studies in gastroenterology, allowing the reader to learn how to evaluate the quality of such studies with respect to measuring outcomes and to make effective use of all types of evidence in patient care. In short, this practical guidebook will be of interest to every medical researcher or gastroenterologist who has ever had a good clinical idea but not the knowledge of how to test it.

• Provides a clear process for understanding, designing, executing, and analyzing translational and clinical research
• Presents practical and step-by-step guidance to help readers take ideas from the lab to the bedside
• Written by a team of experts who cover the breadth of translational research in Gastroenterology
