  1. ISS; injury severity score, SBP; systolic blood pressure, Hb; hemoglobin, RBC; red blood cell transfusion, CI; confidence interval.
  2. Logistic Regression including n = 383 patients without complications and n = 134 patients with complications;
  3. Hosmer-Lemeshow goodness-of-fit test: p = 0.629; Nagelkerke’s R2: 0.156; model chi-square: 58.2, p < 0.001. Sensitivity 16.4% (22/134) correctly predicted patients with complications, specificity 97.1% (372/383) correctly predicted patients without complications; italicized p values indicate statistical significance (p < 0.05).
