Table. Three evaluated models for the dependent variables “surgery,” “complication,” and “death”*.

Factor	Surgery: adjusted OR [95% CI]/p	Complication: adjusted OR [95% CI]/p	Death: adjusted OR [95% CI]/p
Sex
Female	0.58 [0. 53; 0.63] p < 0.001	0.74 [0. 67; 0.82] p < 0.001	0.82 [0.68; 0.98] p = 0.032
Fracture
Acetabular involvement	8.94 [8.05; 9.95] p < 0.001	2.59 [2.31; 2.89] p < 0.001	1.17 [0.95; 1.43] p = 0.146
Type B/C pelvic girdle fracture	5.12 [4.63; 5.67] p < 0.001	1.80 [1. 61; 2. 02] p < 0.001	0.96 [0.78; 1.17] p = 0.663
Extent of injury
Polytrauma	1.08 [0.95; 1.23] p = 0.101	1.48 [1.28; 1.72] p < 0.001	2.27 [1.73; 2.98] p < 0.001
Continuous factors
ISS (Injury Severity Score)	1.03 [1.02; 1.03] p < 0.001	1.04 [1.03; 1.04] p <0.001	1.09 [1.08; 1.10] p <0.001
Age	0.98 [0.98; 0.99] p < 0.001	1.01 [1.01; 1.02] p < 0.001	1.05 [1.04; 1.05] p < 0.001

* As well as the unadjusted and adjusted odds ratios (OR) of the independent variables.

The corresponding references for the discrete factors are: sex, male; fracture: no acetabular involvement or no type B/C pelvic girdle fracture; extent of injury: no polytrauma. CI, Confidence interval; OR, odds ratio
