Event rates and relative risks for all-cause mortality in 497 patients prior to CABG
| Total study population | NGT | Pre-diabetes | Diabetes | |
| (N=497) | (n=170) | (n=219) | (n=108) | |
| Number of deaths, n (%) | 133 (27) | 44 (26) | 51 (23) | 38 (35) |
| Deaths/100 patient-years (95% CI) | 2.7 (2.3 to 3.2) | 2.7 (2.0 to 3.6) | 2.3 (1.7 to 3.0) | 3.6 (2.6 to 5.0) |
| HR (95% CI) | ||||
| Unadjusted model | 1 (ref) | 0.82 (0.55 to 1.23) | 1.34 (0.87 to 2.07) | |
| Age-adjusted and sex-adjusted model | 1 (ref) | 0.67 (0.44 to 1.00) | 0.98 (0.63 to 1.53) | |
| Multivariable model 1* | 1 (ref) | 0.68 (0.45 to 1.03) | 1.07 (0.68 to 1.68) | |
| Multivariable model 2† | 1 (ref) | 0.71 (0.46 to 1.08) | 1.03 (0.65 to 1.64) | |
*Model 1 was adjusted for age, sex, renal function (estimated glomerular filtration rate) and left ventricular ejection fraction.
†Model 2 was adjusted for all variables in model 1, and also body mass index, hypertension, pulmonary disease, peripheral vascular disease, smoking, prior myocardial infarction, prior percutaneous coronary intervention and prior stroke.
CABG, coronary artery bypass grafting; n, number of patients; ref, reference category.
