ISS; injury severity score, SBP; systolic blood pressure, Hb; hemoglobin, RBC; red blood cell transfusion, AIS; abbreviated injury severity, CI; confidence interval. Logistic regression including data from n = 515 patients with multiple trauma; Hosmer-Lemeshow goodness of fit test: p = 0.869; Nagelkerke’s R²: 0.642; model chi-square: 140.5, p < 0.001. Sensitivity 59.4% (19/32) correctly predicted descendents, Specificity 98.8% (477/483) correctly predicted survivors; italicized p values indicate statistical significance (p < 0.05).
