Ensemble Model Performance

(A) Receiver-operating characteristic for ECG+ECHO model (blue line) and echo-only model (green line), displayed as average ± 1 standard deviation (gray) of repeated 5-fold cross-validation test sets. (B) Average precision recall curve displayed similarly to above. Baseline prevalence demarcated by red dotted line. AUROC = area under the receiver-operating characteristic curve; AUPRC = area under precision-recall curve; ECG = electrocardiogram; ECHO = echocardiogram; RVEF = right ventricular ejection fraction.
