Patients were classified regarding the ventilatory support received during the ICU stay: noninvasive mechanical ventilation (NIMV), high-flow nasal cannula (HFNC) and invasive mechanical ventilation (IMV), divided into early IMV (intubation within 24\u2005h) and late IMV (intubation after 24\u2005h).
