The sample median (minimum-maximum) is given for numerical variables. Information regarding positive end-expiratory pressure, FiO₂, mean airway pressure, and PaO₂ were only available for patients with mechanical ventilation. Information was unavailable regarding ambulation (n = 5), mean airway pressure (n = 2), and PaO₂ (n = 1). ICU: Intensive care unit; MELD: Model for end-stage liver disease.
