  1. CI confidence interval, MV mechanical ventilation, SE standard error, IQR interquartile range, ICU intensive care unit. aThe hazard ratio was calculated with the use of Cox proportional-hazards model; bVentilator free days were defined as the number of days between successful weaning from mechanical ventilation and day 28. cICU-free days were defined as the number of days between successful discharge from ICU and day 28; dSupport free days were defined as the number of days between the last day supported and day 28.
