*P values indicate differences between survivors and non-survivors. A value of p<0.05 was considered statistically significant.
†Data were expressed as n/N (%), where N indicated available total cases.
‡Non-invasive and invasive mechanical ventilation were included. Non-invasive mechanical ventilation included bilevel positive airway pressure ventilation or high-flow nasal cannula oxygen therapy.
