Fig. 3: Model performance across age and sex demographic groups.
From: Diagnosis of cardiac conditions from 12-lead electrocardiogram through natural language supervision
a area under the receiver operating characteristic curve (AUROC) performance across 18 cardiac conditions stratified by age groups (12–44, 45–74, and ≥75 years). b AUROC performance stratified by sex (male vs. female). c area under the precision-recall curve (AUPRC) performance across cardiac conditions stratified by age groups. d AUPRC performance stratified by sex. Stars indicate the demographic group with the highest performance when the difference between groups is >0.1; triangles indicate the group with the lowest performance when the difference is >0.1. Cardiac conditions are abbreviated as: AF atrial fibrillation, SVT supraventricular tachycardia, ST sinus tachycardia, SB sinus bradycardia, PVC premature ventricular complexes, PAC premature atrial complexes, PR pacemaker rhythm, AVB atrioventricular block, 1dAVb first-degree atrioventricular block, RBBB right bundle branch block, LBBB left bundle branch block, LVH left ventricular hypertrophy, STTC ST-T changes, PQTI prolonged QT interval, LowQRS low QRS voltages.
