  • AAST-OIS = American Association for the Surgery of Trauma Organ Injury Scale; IAVI = intra-abdominal vascular injury; ICU = intensive care unit; SD = standard deviation.

  • * Statistical tests were performed excluding combined injuries so as to fit the test assumption of nonoverlapping data.

  • Kruskal–Wallis test.

  • χ2 test.
