  1. AISϕ is the number of patients with an AIS > 2. Hemostatic procedure was defined as performing angioembolization or hemostatic surgery within the first six hours of management from admission
  2. Data are reported as mean ± SD or median [Q1–Q3]
  3. GCS glasgow coma scale, Hb hemoglobin, HR heart rate, Ht hematocrit, H6 Over the first 6 h after admission, H6-H12 between H6 and H12 after admission, ICU intensive care unit, ISS injury severity score, MBP mean blood pressure, PT prothrombin time, RBC red blood cells, SAPS simplified acute physiology score, SD standard deviation, SBP systolic blood pressure, SpO2 pulse oximeter oxygen saturation
  4. εPatient transfused with red blood cells over the first six hours of admission
  5. #Non-transfused patients were compared with transfused patients
  6. *Two-sided level of significance was fixed at 5%
