*Among 366 study sample, 39% (N = 144) were identified as severe TBI patients (head AIS ≥ 3, abnormal head CT); 5% (N = 20) died at admission.
**Transportation type has four categories. Private Vehicle combines “Private vehicle” and “Taxi”; Helicopter includes “Helicopter” only; Ambulance combines “Ambulance (doctor)”, “Police”, and “Firefighter’; Other/Unknown combines “Other” and “Unknown
