  1. ALI, acute lung injury; BMI, body mass index; GCS, Glasgow Coma Scale; ITH, time of injury to hospital; TBI, traumatic brain injury.
  2. aAdjusted for age, sex, BMI, ITH, major extracranial injury, admission departments, cause of injury and treatment measures.
  3. bThe injury score was calculated according to the number of injured regions.
  4. cRepresents the glutamate level on admission.
