ROC curve on the prediction of in-hospital mortality by the model combining various predictive factors for the derivation cohort (age >70, the presence of comorbidities, number of comorbidities, hematemesis on presentation, initial systolic blood pressure <100 mm Hg, in-hospital ulcer bleeding, non–H pylori–related ulcers, rebleeding, and need for surgery) identified in the derivation cohort by using stepwise logistic regression. The AUC is

ROC curve on the prediction of in-hospital mortality with the combination of pre-endoscopic predictive factors only for the derivation cohort (including age >70, presence of comorbidities, number of comorbidities, hematemesis on presentation, initial systolic blood pressure <100 mm Hg, in-hospital ulcer bleeding). The AUC is
