Comparison of men versus women (reference = women at each level of CAD) of 5-year mortality at each level of CAD severity

CAD severity	Unadjusted model		Adjusted model*
	HR for M vs F (95% CI)	P value	HR for M vs F (95% CI)	P value
Overall,† stratified by CAD severity	1.03 (0.96–1.10)	.4951	1.29 (1.20–1.40)	<.0001
No CAD	1.35 (1.15–1.59)	.0002	1.56 (1.32–1.85)	<.0001
Nonobstructive	1.20 (1.04–1.38)	.0113	1.43 (1.23–1.65)	<.0001
Obstructive	0.87 (0.79–0.95)	.0030	1.16 (1.05–1.28)	.0020

^*Adjusted model includes the following covariates: age, race, BMI, prior MI, diabetes, hypertension, hyperlipidemia, peripheral vascular disease, congestive heart failure, chronic obstructive pulmonary disease, renal disease, smoking history, noncardiac Charlson comorbidity index >1, and year of cath. Interaction between CAD severity and sex was significant in both the unadjusted and adjusted models (interaction P < .01 for both).

^†Overall sex HRs are estimated by fitting the unadjusted Cox model stratified by CAD severity and the adjusted Cox model stratified by CAD severity.
