Severity of acute gastrointestinal injury grade is a good predictor of mortality in critically ill patients with acute pancreatitis

Figure 3 Receiver operating characteristic curve analysis of scores for predicting mortality in acute pancreatitis patients in the intensive care unit. A: Receiver operating characteristic (ROC) curve analysis of acute gastrointestinal injury (AGI) grade [area under curve (AUC): 0.854], Acute Physiology and Chronic Health Evaluation (APACHE) II score (AUC: 0.739), Modified Marshall score (AUC: 0.785), and Ranson score (AUC: 0.72) for predicting mortality; B: ROC curve analysis of AGI grade + APACHE II score (AUC: 0.893) and APACHE II score (AUC: 0.739) for predicting mortality; C: ROC curve analysis of AGI grade + Modified Marshall score (AUC: 0.895) and Modified Marshall score (AUC: 0.785) for predicting mortality; D: ROC curve analysis of AGI grade + Ranson score (AUC: 0.89) and Ranson score (AUC: 0.72) for predicting mortality. AGI: Acute gastrointestinal injury; APACHE: Acute Physiology and Chronic Health Evaluation.
