Association of risk group with composite outcome
| Risk group | Events, n (%) | Hazard ratio (95% CI) | P value |
|---|---|---|---|
| Full model with race | |||
| Low risk | 2/50 (4) | 1 | |
| Intermediate risk | 10/108 (9.3) | 2.77 (0.61–12.65) | 0.189 |
| Higher risk | 42/108 (38.9) | 12.47 (3.01–51.62) | <0.001 |
| Highest risk | 33/50 (66) | 41.15 (9.79–173.01) | <0.001 |
| P value for trend | <0.0001 | ||

Risk stratification was based on percentiles of the linear predictor (low risk: <16th, intermediate risk: 16th to 50th, higher risk: 50th–84th, highest risk: >84th).
