Development and external validation of models to predict acute respiratory distress syndrome related to severe acute pancreatitis

Figure 2 Receiver operating characteristic curves of different predictive models in derivation and validation cohort. A: Receiver operating characteristic (ROC) curves of severe acute pancreatitis (SAP) predictive models in derivation cohort; B: ROC curves of SAP predictive models in validation cohort; C: ROC curves of acute respiratory distress syndrome (ARDS) predictive models in derivation cohort; D: ROC curves of ARDS predictive models in validation cohort. BISAP: Bedside index for severity in acute pancreatitis; qSOFA: Quick sequential organ failure assessment; SIRS: Systemic inflammatory response syndrome.
