Table 4 Regression results from analyses looking at differences in outcomes (death at 90 days, ventilator days, ICU-free days, and hospital-free days) by ARDS status
| Â | ARDS at mechanical ventilation onset vs never developed ARDS | ARDS after mechanical ventilation onset vs never developed ARDS | ARDS after mechanical ventilation onset vs ARDS at mechanical ventilation onset |
|---|---|---|---|
Odds ratio of death at 90 days (95% CI) | 1.61 (1.21, 2.14) | 1.54 (1.07, 2.20) | 0.95 (0.63, 1.45) |
Mean difference in ventilator-free days (95% CI) | − 3.82 (− 5.19, − 2.44) | − 5.57 (− 7.32, − 3.82) | − 1.75 (− 3.78, 0.28) |
Mean difference in ICU-free days (95% CI) | − 2.95 (− 4.09, − 1.81) | − 4.99 (− 6.43, − 3.54) | − 2.04 (− 3.72, − 036) |
Mean difference in hospital-free days (95% CI) | − 3.04 (− 5.21, − 0.87) | − 5.95 (− 8.71, − 3.20) | − 3.05 (− 6.03, − 0.08) |
