SE = standard error of the mean.
adj. % = adjusted percent. Proportion with associated outcome within BAC:AA/AD group is adjusted for ISS.
ICU = Intensive Care Unit, TISS 24 = Therapeutic Intervention Scoring System for first 24 hours, LOS = Length of stay, PRBC = Packed red blood cells, cc = cubic centimeters.
