Nomogram for prediction of six-month mortality following endovascular treatment of delayed post-pancreatectomy hemorrhage

Figure 4 Performance evaluation of the nomogram predicting six-month mortality after endovascular treatment for delayed post-pancreatectomy hemorrhage. A: Receiver operating characteristic curve showing an area under the receiver operating characteristic curve of 0.943 (95% confidence interval: 0.781-0.958), indicating excellent discrimination; B: Calibration plot comparing predicted vs observed probabilities. Both the apparent and bias-corrected curves align closely with the ideal line, suggesting good calibration; C: Decision curve analysis demonstrating the clinical utility of the model, with greater net benefit across a range of threshold probabilities compared to treat-all or treat-none strategies. ROC: Receiver operating characteristic; AUC: Area under curve.
