  1. Numerical variable is presented as median and interquartile range (IQR).
  2. ECLS: Extracorporeal life support. PaO 2 /FiO 2 ratio: The arterial oxygen tension (PaO 2 ) divided by the fraction of inspired oxygen (FiO 2 ). INR: International normalized ratio. aPTT: Activated partial thromboplastin time. TIC: Trauma induced coagulopathy (INR > 1.3 or aPTT > > 35). *p < 0.05. The maximum of the detectable values.
