Performance and Calibration of Included Models for External Validation

Panel A: Forest plot showing the independent external validation results of 4 models (Cho et al., Sangha et al., Huang et al., and van de Leur et al.) in the full cardiac magnetic resonance cohort and the augmented heart failure cohort. The plot displays area under the receiver-operating characteristic curve values with their 95% CI. Panel B: Calibration plot for the external validation. The mean predicted probabilities vs observed proportions, shown using quantile binning (10 bins). The “Perfect Calibration” line indicates ideal model calibration. CMR = cardiac magnetic resonance; HF = heart failure; AUROC = area under the receiver-operating characteristic curve; Sens = Sensitivity; Spec = Specificity; PPV = positive predictive value; NPV = negative predictive value; ECG = electrocardiogram; CGMH = Chang Gung Memorial Hospital.
