ROC curve of 3 outcomes. The ROC results of six machine learning models for death, readmission and MACEs. For each outcome, models built by general information are shown in model 1, by four domains of CHF-PRO are shown in model 2, by general information and CHF-PRO are shown in model 3, and by general information and CHF-PRO and adjusted parameters are shown in model 4. FPR, false positive rate; TPR, true positive rate
