Unadjusted Odds Ratios for Sudden Cardiac Death

Parameter	OR (95% CI)	P Value
Black race	3.0 (1.6 to 5.7)	<0.01
Moderate or severely dilated LV vs normal	2.1 (1.3 to 3.4)	<0.01
Severely dilated LV vs moderately or mildly dilated or normal	4.0 (1.7 to 9.3)	<0.01
LVEF ≤35%	2.0 (1.4 to 2.9)	<0.01
LVEF ≤35% with normal LV size or mild LV dilatation*	1.5 (1.0 to 2.3)	0.06
LVEF ≤35% and either moderate or severe LV dilatation*	2.6 (1.4 to 4.7)	<0.01
LVEF ≤35% and severe LV dilatation*	4.9 (1.9 to 12.7)	<0.01

EF indicates ejection fraction; LV, left ventricle; OR, odds ratio.
