خلاصه	The Glasgow-Blatchford score (GBS), developed by Blatchford et al. in 2000, is a 23-point risk stratification tool for predicting the need for intervention (transfusion, endoscopic therapy, surgery) in patients presenting with acute upper gastrointestinal bleeding. It integrates clinical and laboratory data to identify low-risk patients who may be candidates for outpatient or non-interventional management.	The Wells score, developed by Wells et al. in 1994, is a clinical prediction rule that stratifies patients into low, intermediate, or high pretest probability of deep vein thrombosis (DVT). It combines seven clinical features to guide diagnostic testing decisions and reduce unnecessary imaging in suspected DVT patients.
