  1. ARDS acute respiratory distress syndrome
  2. aNumber of patients who developed this complication after the first day of ARDS onset as a proportion of those patients without this complication until ARDS onset
  3. bIncidence rate of the complication after the first day of ARDS onset per 1000 days of mechanical ventilation in those patients without this complication until ARDS onset
  4. cRemaining days for analysis of a total of 1249 days of mechanical ventilation after ARDS onset in university hospitals and 988 days in non-university hospitals (observation only during mechanical ventilation and up to 28 days after initiation of mechanical ventilation)
