Table 4 Comparison of mortality and major adverse cardiovascular events after CABG between sex groups using Cox regression and inverse probability weighting

From: Sex and age difference in risk factor distribution, trend, and long-term outcome of patients undergoing isolated coronary artery bypass graft surgery

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 0.72 0.57 0.91 0.01
  1. Model 1: Unadjusted Cox regression. Model 2: Multivariate Cox regression for outcome. Model 3: Inverse probability weighting (IPW)
  2. MACE: Major adverse cardiovascular event, HR: hazard ratio, CI: confidence interval
