About
Because of the complexity of the functional gastrointestinal disorders, it has been difficult over the years to determine which outcome measures and endpoints should be used in clinical trials of pharmaceutical agents. Some trials have used a global relief measure as a primary endpoint, while others have focused on symptom improvement. This working team conducted a systematic review and meta-analysis of the psychometric and performance characteristics of primary endpoints used in large multi-center therapeutic trials for irritable bowel syndrome using pharmacological approaches.
