  1. aTBI, traumatic brain injury; 95% CI, 95% confidence interval; FFP, fresh frozen plasma; pRBC, packed red blood cell; RISC, Revised Injury Severity Classification. Logistic regression analysis was performed with mortality as a dependent variable and FFP:pRBC ratio, RISC score and emergency operations as independent variables according to the presence or absence of TBI.
