TABLE 3.

Performance metrics for the RF classifier on the test set in various categories. Imbalance correction was applied to the NG+CR vs. LVH classification using Random Over Sampler

Features	Categories	Threshold	Accuracy (%)	Specificity (%)	Sensitivity (%)	AUC/ROC	AUC/PR
6 clinical	NG vs. CR + LVH	0.5	79	73	84	0.85	0.82
6 clinical + 26 ECG	NG vs. CR + LVH	0.5	87	75	97	0.91	0.89
6 clinical + 26 ECG + oversampling	NG + CR vs. LVH	0.5	88	97	44	0.87	0.67
6 clinical + 26 ECG + oversampling	NG + CR vs. LVH	0.4	89	93	67	0.89	0.5

Abbreviations: AUC/PR, area under the precision‐recall curve; AUC/ROC, area under the receiver operating curve; CR, concentric remodeling; ECG, electrocardiogram; LVH, left ventricular hypertrophy; NG, normal geometry.
