Six predictors remaining in the final model were suggested to be independent risks for predicting DVT in the patients with pelvic-acetabular fractures: age (OR, 1.037; 95% CI, 1.013–1.062; P = 0.002), BMI(OR, 1.253; 95% CI, 1.120–1.403; P < 0.001); IAA (OR, 2.734; 95% CI, 0.847–8.829; P = 0.093), HGB (OR, 0.970; 95% CI, 0.954–0.986; P < 0.001), D-Dimer(OR, 1.154; 95% CI, 1.016–1.310; P = 0.027) and FIB (OR, 1.286; 95% CI, 1.024–1.616; P = 0.002; Table 2). Here, CYGB is linked to deep vein thrombosis.
