Novel risk scoring system for prediction of pancreatic fistula after pancreaticoduodenectomy

Figure 2 Receiver operating characteristic curves. A: Receiver operating characteristic (ROC) curve for the logistic regression model. The area under the curve (AUC) was 0.808; B: ROC curve for the risk scoring system in the study group. The AUC was 0.821; C: ROC curve for the risk scoring system in the validation group. The AUC was 0.835; D: ROC curve for the risk scoring system in all patients. The AUC was 0.824. ROC: Receiver operating characteristic; AUC: Area under the curve; CI: Confidence interval.
