  • For continuous variables, odds ratio represents the increase in the odds of mortality for each 1 unit increment in the predictor variable. CI indicates confidence interval; COPD, chronic obstructive pulmonary disease; CVD, cerebrovascular disease; IABP, intra-aortic balloon pump; and PVD, peripheral vascular disease.
