Clinical outcomes of patients with acute pulmonary oedema classified by oedema fluid-to-plasma protein (EF/PL) ratio
| EF/PL <0.65 | EF/PL ≥0.65 | p-value# | |
| All subjects | 175 | 215 | |
| Ventilator-free days | 10 (0–26) | 0 (0–22) | 0.006 |
| Hospital mortality % | 50 | 61 | 0.022 |
| Subgroup with interval from intubation to oedema fluid sampling <3 h | 103 | 97 | |
| Ventilator-free days | 22 (0–26) | 4 (0–23) | <0.001 |
| Hospital mortality % | 41 | 65 | 0.012 |
Data are presented as n or median (interquartile range), unless otherwise stated. #: comparison of EF/PL groups by Chi-squared for hospital mortality. Ventilator-free days were compared using the Mann–Whitney U-test.
