The 2nd column contains general demographics, while the 3rd and 4th columns contain detailed information about two subgroups (mildly edematous patients and severely edematous patients). The Marshall score was obtained from the first CT scan image; the three severely edematous subjects who showed a Marshall score less than 2 later developed severe cerebral edema. MVA, motor vehicle accident.
