  • *P values indicate differences between diabetes and non-diabetes. A value of p<0.05 was considered statistically significant.

  • †Non-invasive mechanical ventilation and invasive mechanical ventilation were included. Non-invasive mechanical ventilation included bilevel positive airway pressure ventilation or high-flow nasal cannula oxygen therapy.

  • ICU, intensive care unit.
