Performance of CNN to detect PH with fewer than 12 ECG leads.

	AUC	Sensitivity	Specificity	PPV	NPV
Detecting PH using 2 ECG leads (leads I and V2)	0.84 (0.83-0.86)	0.78 (0.75-0.81)	0.76 (0.74-0.77)	0.45 (0.42-0.48)	0.93 (0.92-0.94)
Detecting PH using ECG lead V2	0.83 (0.82-0.85)	0.72 (0.68-0.75)	0.8 (0.78-0.81)	0.47 (0.44-0.5)	0.92 (0.91-0.93)
Detecting PH using ECG lead I	0.81 (0.79-0.83)	0.77 (0.73-0.8)	0.7 (0.68-0.71)	0.39 (0.37-0.42)	0.92 (0.91-0.93)

AUC=area under the receiver operating characteristic curve; PH=pulmonary hypertension; PPV=positive predictive value; NPV=negative predictive value.
