| Alcohol consumption, units/day | Number of deaths (percentage of total number of patients in the group) | HR unadjusted (95% CI) | HR adjusted* (95% CI) |
|---|---|---|---|
| No alcohol n=25 | 4 (16) | 0.83 (0.30 to 2.30) | 0.81 (0.28 to 2.35) |
| ≤1 n=227 | 42 (18.5) | 1.0 (baseline) | 1.0 (baseline) |
| 2–3 n=57 | 4 (7.0) | 0.35 (0.12 to 0.98) | 0.23 (0.08 to 0.68) |
| More than 3 n=12 | 3 (25.0) | 1.42 (0.44 to 4.57) | 1.51 (0.43 to 5.30) |
