  1. AIS, abbreviated injury scale; CI, confidence intervals; GCS, Glasgow coma scale; ISS, injury severity score; OR, odds ratio; SBP, systolic blood pressure; TAE, transcatheter arterial embolization.
  2. * p values significant at (p < 0.05).
  3. † Model 1: multiple logistic regression analysis.
  4. ‡ Model 2: multiple logistic regression analysis including propensity scores; propensity scores were calculated based on age, gender, no. of comorbidities, SBP, GCS, ISS, and AIS (pelvic, head, thorax, abdomen).
