Receiver operating characteristic (ROC) curve of total infusion volume for predicting the risk of anastomotic leakage. ROC analysis was performed to estimate the cutoff value of intraoperative fluid volume for predicting the risk of anastomotic leakage (n = 272). The ROC curve had area under the curve (AUC) of 0.59. The cutoff value was estimated to be 3,792 mL, which had a sensitivity of 62% and a specificity of 54% (P = 0.0310)
