  1. SD standard deviation, ICU intensive care unit, Q1–Q3 25th–75th percentile
  2. °For tracheostomized patients, length of stay was calculated from the “approximate” date of tracheostomy
  3. *Mortality was evaluated according to the vital status at 28/60/90 days from acute respiratory distress syndreom onset or from the “nearest recorded” date of tracheostomy in non tracheostomized and tracheostomized patients, respectively. If the patient was discharged alive before 28/60/90 days, we considered the patient as alive
