On day 1, mean SOFA score was 9 ± 3; median (IQR) PaO<sub>2</sub>/FiO<sub>2</sub> ratio 119 (89, 142), median (IQR) FiO<sub>2</sub> 70% (50%, 99%) and mean (±SD) positive end expiratory pressure (PEEP) 11 (±3) cmH<sub>2</sub>O. On day one, 10.5% (n = 21) received lung protective ventilation (LPV) (tidal volume ≤6.5 mL/kg predicted body weight and plateau pressure or peak pressure ≤30 cm H<sub>2</sub>O). Adjunctive therapies were received by 86% (n = 172) of patients at some stage from enrolment to day 28. Systemic steroids were most used (n = 127) followed by neuromuscular blockers (n = 122) and prone positioning (n = 27). Median ventilator-free days (IQR) to day 28 was 5 (0, 20).
