Central clinical data of study participants. Ages were compared using Student's t-test, and sexes were compared using Fisher's Exact test.

BE, base excess, GCS, Glasgow Coma Scale, ICU, intensive care unit, INR, international normalized ratio; ISS, injury severity score, PT, polytrauma; PTT, partial thromboplastin time; RBC, red blood cell; RR, Riva-Rocci, SEM, standard error of the mean; TASH score, trauma associated severe hemorrhage score.
