Development and prospective validation of a machine learning model to predict mortality in cirrhosis with esophageal variceal bleeding

Figure 3 Performance evaluation of the random forest model in the prospective validation cohort. A: Receiver operating characteristic (ROC) curve showing the relationship between true-positive rate and false-positive rate. The dashed line represents random prediction; B: Precision-recall curve demonstrating the model’s predictive performance across different classification thresholds. AUC: Area under the curve.
