Hazard ratios for all-cause mortality after coronary angiography (n = 30 358), by treatment subgroup*
| Treatment | No. (%) of patients | Unadjusted HR (95% CI) | Adjusted HR (95% CI) | ||
|---|---|---|---|---|---|
| Non–First Nations (n = 29 652) | First Nations (n = 706) | Partial adjustment† | Full adjustment‡ | ||
| Medical management | 2 365 (8.0) | 61 (8.6) | 0.99 (0.76–1.28) | 1.40 (1.09–1.80) | 1.38 (1.07–1.77) |
| PCI | 2 672 (9.0) | 69 (9.8) | 1.24 (0.98–1.57) | 1.38 (1.06–1.80) | 1.38 (1.06–1.80) |
| CABG | 997 (3.4) | 17 (2.4) | 0.67 (0.42–1.07) | 0.89 (0.55–1.44) | 0.91 (0.56–1.47) |
Note: CABG = coronary artery bypass grafting, CI = confidence interval, HR = hazard ratio, MI = myocardial infarction, PCI = percutaneous coronary intervention.
