Figure 1 Receiver operating characteristic curve. A: Receiver operating characteristic (ROC) curve for the predictive scoring system; B: Drain amylase on postoperative day 3 in the low risk group. Area under the receiver operator characteristics curve was 0.838. C: Drain amylase on postoperative day 2 and 3 in high risk group. Areas under the receiver operator characteristic curves were 0.756 and 0.761, respectively. POD: Postoperative day.
