Categorical Predictors of Appropriate Shock

	Hazard Ratio
Estimate
Monomorphic VT	4.56 (1.2; 17.28)
History of sudden death	6.45 (1.40; 29.83)
Channelopathy	0.58 (0.13; 2.53)
Cardiac Function	0.49 (0.06; 3.95)
Performance
AUC	0.79
AUC_OC^*	0.72

Hazard ratios obtained from Cox proportional hazards regression. Time from diagnosis to evaluation modeled using restricted cubic spline terms with knots placed at the 10th, 50th, and 90th percentiles.

AUC_OC obtained using 1,000 bootstrap resamples.

AUC – Area under the curve; AUC_OC – optimism correct area under the curve; VT – ventricular tachycardia; SCD – sudden cardiac death
