Table 1.

Showing baseline characteristics of EMF cases.

Variable	Overall N = 155	Group A N = 124	Group B N = 31	P-value
Median age in years (1QR)	13 (10–18)	14 (10.5–19.0)	12 (10.0–14.75)	0.0940
Female gender, n (%)	71 (45.8)	60 (48.4)	11 (35.5)	0.1987
EMF phenotype
Right ventricular EMF, n (%)	105 (67.7)	83 (66.9)	22 (71.0)	0.6634
Biventricular EMF, n (%)	50 (32.3)	41 (33.1)	9 (29.0)

No cases of pure left ventricular EMF were seen. The majority of cases with biventricular EMF had predominant RV involvement (n = 42, 84%) with the rest (n = 8, 16%) have equal involvement of both right and left ventricles.
