  • The models were adjusted for age, sex, body mass index categories (<30 or >30), Simplified Acute Physiology Score, Charlson Comorbidity Index (0, 1, >2), mechanical ventilation (yes/no), treatment limitations (yes/no) and SARS-CoV-2 wave (wave 1/waves 2–3).

  • *Statistically significant differences between groups, p<0.05.

  • IHT, interhospital transfer.
