Preoperative C-reactive protein and textbook outcome following pancreaticoduodenectomy for pancreatic head adenocarcinoma

Figure 3 Receiver operating characteristic curve. A: Receiver operating characteristic curve of preoperative C-reactive protein alone for predicting non-textbook outcome. The area under the curve was 0.815 (95% confidence interval: 0.722-0.896). The Youden-derived cut-off was C-reactive protein ≥ 13.0 mg/L, with 66.0% sensitivity and 90.6% specificity. The diagonal dashed line represents the reference line; B: Receiver operating characteristic curves of the multivariable models for textbook outcome achievement. The area under the curve was 0.819 for the primary preoperative model and 0.820 for the bilirubin-adjusted sensitivity model. The diagonal reference line is shown for comparison. AUC: Area under the curve; CI: Confidence interval; ROC: Receiver operating characteristic; TO: Textbook outcome; CRP: C-reactive protein.
