Table 4 Subgroup analysis: association between primary intervention (Laparotomy/TAE) and in-hospital mortality

From: Comparison between laparotomy first versus angiographic embolization first in patients with pelvic fracture and hemoperitoneum: a nationwide observational study from the Japan Trauma Data Bank

Subgroup Crude OR 95% CI Adjusted OR 95% CI
SBP      
  ≤ 65 1.50 (0.52-4.42) 1.05 (0.44-3.03)
  66-89 1.54 (0.61-3.92) 1.50 (0.56-4.05)
  ≥ 90 1.52 (0.59-3.74) 1.15 (0.44-3.03)
Pelvic AIS      
  ≤3 1.64 (0.70-3.84) 0.73 (0.41-1.86)
  ≥ 4 2.68 (1.32-5.44*) 1.84 (0.85-3.98)
Abdomen AIS     
  ≤3 1.22 (0.58-2.47) 0.87 (0.41-1.86)
  ≥ 4 2.37 (0.88-6.70) 2.10 (0.78-5.66)
  1. AIS, abbreviated injury scale; CI, confidence intervals; OR, odds ratio; SBP, systolic blood pressure; TAE, transcatheter arterial embolization.
  2. *p values significant at (p < 0.05).
  3. †Adjusted OR: 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).
