  1. ISS; injury severity score, RBC; red blood cell transfusion, AIS; abbreviated injury severity, CI; confidence interval for regression coefficient. Robust multiple linear regression including data from n = 514 patients (R = 0.357, p < 0.001; Durbin Watson statistics 2.008). Confidence intervals and standard errors based on 1000 bootstrap samples; italicized p values indicate statistical significance (p < 0.05).
