Data are presented number (%).
ECMO = extracorporeal membrane oxygenation.
aPercentages may not total 100 because of rounding. Patients without a disease severity score on admission day (279, 9.1%) or died on admission day (2, 0.1%) were also excluded from this analysis; b1, no limitation of daily activities; 2, limitation of daily activities but no need for supplemental oxygen therapy; 3, need for supplemental oxygen therapy via nasal cannula; 4, need for supplemental oxygen therapy via facial mask; 5, need for high-flow supplemental oxygen therapy or non-invasive mechanical ventilation; 6, need for invasive mechanical ventilation; 7, multi-organ failure or need for ECMO therapy.
