Traditional Cox Proportional Hazards Models and Subdistribution Competing‐Risk Models for Association of Frailty Status With CVD and Non‐CVD Mortality
| Frailty Status | Hazard Ratio (95% CI)a | |||||
|---|---|---|---|---|---|---|
| CVD Mortality | Non‐CVD Mortality | |||||
| Events, n | Cox Proportional Hazards Model | Subdistribution Model | Events, n | Cox Proportional Hazards Model | Subdistribution Model | |
| Robust | 81 | 1.00 (referent) | 1.00 (referent) | 158 | 1.00 (referent) | 1.00 (referent) |
| Intermediate stage | 242 | 1.55 (1.20–1.99) | 1.38 (1.07–1.78) | 472 | 1.62 (1.35–1.94) | 1.56 (1.30–1.87) |
| Frail | 122 | 2.73 (2.03–3.68) | 1.98 (1.45–2.71) | 198 | 2.57 (2.06–3.21) | 2.16 (1.73–2.70) |
CI indicates confidence interval; CVD, cardiovascular disease.
