Performance evaluation in terms of rehospitalization for heart failure prediction model in the derivation and validation cohorts. (A) The area under the receiver operating characteristic curve (AUC) of the rehospitalization prediction model was 0.794 [95% confidence interval (CI): 0.756–0.832] in the derivation cohort. (B) The AUC of the rehospitalization prediction model was 0.812 (95% CI: 0.758–0.866) in the validation cohort. (C,D) Calibration plot of the mortality prediction model in the derivation and validation cohort. The dashed diagonal line represents perfect calibration. The x-axis is the predicted probability estimated by the model and the y-axis is the actual probability.
