Kaplan-Meier estimates of probability of unassisted breathing and live discharge from ICU from randomization to D28. In keeping with previous trials [21, 22], unassisted breathing is defined as (1) extubated with supplemental oxygen or room air, or (2) open T-tube breathing, or (3) tracheostomy mask breathing, or (4) continuous positive airway pressure (CPAP) ≤ 5 cm H20 without pressure support and with no return to assisted breathing or death within 48 h. Participants receiving pressure support via non-invasive ventilation or CPAP > 5 cm H2O via any medium were defined as receiving assisted ventilation. NAVA = neurally adjusted ventilatory assist; PSV = pressure support ventilation
