| Outcomes | Low tertile (≤30.2, n=164) | Middle tertile (30.2–36.2, n=165) | High tertile (>36.2, n=165) | P value |
|---|---|---|---|---|
| 30-day mortality | 40 (24.4%) | 22 (13.3%) | 15 (9.1%) | <0.001 |
| Hospital mortality | 41 (25.0%) | 22 (13.3%) | 15 (9.1%) | <0.001 |
| Length of ICU stay, days | 6.9 (3.9, 13.8) | 5.0 (3.0, 8.6) | 4.0 (2.9, 7.2) | <0.001 |
| Length of hospital stay, days | 12.6 (7.4, 18.9) | 10.4 (6.2, 15.0) | 8.5 (5.6, 13.0) | <0.001 |
| MV rate | 124 (75.6%) | 121 (73.3%) | 115 (69.7) | 0.477 |
