Comparative diagnostic utility of Rockall and Glasgow-Blatchford scores in non-variceal upper gastrointestinal bleeding: a systematic review and meta-analysis.

Introduction: The Rockall score and Glasgow-Blatchford score (GBS) are two scoring systems validated in the evaluation of upper gastrointestinal bleeding (UGIB). However, no meta-analysis exists to summarize the current data and clarify the use of Rockall score and GBS focusing on non-variceal UGIB. We aimed to evaluate and compare the utility of the Rockall score and GBS in predicting clinical outcomes in non-variceal UGIB.

Collagenous Gastritis Is an Underdiagnosed Cause of Anemia and Abdominal Pain: Systematic Scoping Review.
