| Patients, n (%) | 1,539 | 1,077 (70.0) | 204 (13.3) | 258 (16.8) | – |
| 30-day ICU mortality | 261 (17.0) | 170 (15.8) | 36 (17.6) | 55 (21.3) | 0.1 |
| In-hospital mortality | 418 (27.2) | 268 (24.9) | 69 (33.8) | 81 (31.0) | 0.008 |
| LOS in ICU (day) | 6.8 (4.5, 11.6) | 6.8 (4.5, 11.7) | 7.4 (4.7, 11.9) | 6.4 (4.6, 10.2) | 0.375 |

Data are displayed as the median (IQR) and n (%). P values comparing groups are the chi-squared test for categorical variables. ARDS, acute respiratory distress syndrome; ICU, intensive care unit; LOS, length of stay.
