  1. Data are presented as median (interquartile range) except for female/male ratio and acute renal failure. For age, the full range is given. * P < 0.05; ** P < 0.001
  2. BMI = body mass index, SOFA = sequential organ failure assessment, LIS = lung injury score, TV/kg pred. BW = tidal volume per kilogram predicted bodyweight, PIP = plateau inspiratory pressure, PEEP = positive end-exspiratory pressure.
