BMI, body mass index; SBP ≤ 90, systolic blood pressure ≤ 90 mmHg; GCS ≤ 8, Glasgow coma scale ≤ 8 points; CPR, cardiopulmonary resuscitation; CT, computed tomography; P/F-ratio, PaO2/FiO2-ratio; Covariates of the multivariable analysis included the most significant variables of the univariable analysis (p < 0.001).
