EM: evacuable mass, GCS: Glasgow Coma Scale, ICU: Intensive Care Unit, NEM: non-evacuable mass, TCDB CT: Traumatic Coma Data Bank Computed tomography.
TCDB CT was grouped in two groups: one best TCDB CT scan classification type I, II and evacuable mass (EM) and the other worst TCDB CT scan type III, IV and non-evacuable mass (NEM).
