Comparison of mortality and major adverse cardiovascular events after CABG between sex groups using Cox regression and inverse probability weighting

Sex	Outcome	Model	HR	CI 95%		P value*
				Lower	Higher
Men versus women	Mortality	Model 1	0.91	0.84	0.98	0.01
		Model 2	0.85	0.78	0.93	< 0.001
		Model 3	1.00	0.79	1.28	0.98
	MACE	Model 1	0.81	0.77	0.85	< 0.001
		Model 2	0.82	0.77	0.87	< 0.001
		Model 3	0.72	0.57	0.91	0.01

Model 1: Unadjusted Cox regression. Model 2: Multivariate Cox regression for outcome. Model 3: Inverse probability weighting (IPW)

MACE: Major adverse cardiovascular event, HR: hazard ratio, CI: confidence interval
