Multivariable Competing Risk Regression Analysis in the Study Population (n=1019) Based on the Fine–Gray Proportional Subhazards Model (Primary Composite Events=69; Noncardiac Deaths=10)

	Subhazard Ratio	P Value
(A) Model 1 (with standard major ACC/AHA SCD risk factors included in analysis)
Age, y	1.04 [1.02–1.07]	<0.001
Atrial fibrillation during follow‐up	1.39 [1.11–1.69]	<0.001
LV‐GLS (for every % worsening)	1.11 [1.05–1.22]	<0.001
Surgical myectomy	0.44 [0.25–0.72]	<0.01
Following potential additional predictors were considered for analysis, but were not significant: standard ACC/AHA major SCD risk factors (none, 1, ≥2), sex, maximal LVOT gradient, medical therapy
(B) Model 2 (with ESC risk score included in analysis)
Atrial fibrillation during follow‐up	1.47 [1.17–2.21]	<0.001
LV‐GLS (for every % worsening)	1.13 [1.08–1.22]	<0.001
Surgical myectomy	0.42 [0.22–0.64]	<0.01
Following potential additional predictors were considered for analysis, but were not significant: ESC risk score, sex, medical therapy

ACC/AHA indicates American College of Cardiology and American Heart Association; ESC, European Society of Cardiology; LV‐GLS, left ventricular global longitudinal strain; LVOT, left ventricular outflow tract; SCD, sudden cardiac death.
