  1. Values are displayed as means ± SD or as medians [interquartile range] when appropriate. Normal distribution was assessed with the Kolmogorov–Smirnov test
  2. FiO2 denotes fraction of inspired oxygen,
  3. PaCO2 partial pressure of arterial carbon dioxide, and PaO2 partial pressure of arterial oxygen
  4. aThe body-mass index is the weight in kilograms divided by the square of the height in meters
  5. bThe Simplified Acute Physiology Score (SAPS) II was calculated from 17 variables at enrolment, information about previous health status and information obtained at admission. Scores range from 0 to 163, with higher scores indicating more severe disease
