  • Note:—Variables are presented as mean (standard deviation) or number (percentage).
  • GCS indicates Glasgow Coma Scale; ICU, intensive care unit; SD, standard deviation; MVA, motor-vehicle collision.
  • ↵a Hematoma was defined as an area spontaneously hyperdense on the first CT scan.
  • ↵b Contusion was defined as a focal area appearing hypodense or of mixed density on the CT scan.
