Independent Predictors of SCD (Multivariate Modeling)—Model Not Including CAD Severity in All Women

Predictor	n=748, 27 Events		P Value (Sensitivity Analysis)a n=751, 30 Events
	HR (95% CI)	P Value
Age, y	1.06 (1.02–1.10)	0.003	0.006
Diabetes mellitus	2.69 (1.21–6.01)	0.016	0.018
History of depression	2.28 (1.03–5.05)	0.041	0.006
Ever smoking	3.01 (1.25–7.23)	0.014	0.015
QTc, per 10 ms	1.14 (1.02–1.27)	0.024	0.009

CAD indicates coronary artery disease; CI, confidence interval; HR, hazard ratio; SCD, sudden cardiac death.

^aThe sensitivity analyses assume the 3 women with no obstructive CAD and missing classifiable mortality information all have SCD.
