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

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

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)

AIS, abbreviated injury scale; CI, confidence intervals; OR, odds ratio; SBP, systolic blood pressure; TAE, transcatheter arterial embolization.
*p values significant at (p < 0.05).
†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).
