  • Variables marginally associated in the univariate analysis (p<0.15) were included in the final multivariate logistic regression model. Model fit: AUROC: 0.80; r2=0.28. Bold values denote p<0.05.

  • AUROC, area under the receiver operating characteristic curve; HP, hemoperitoneum; ISS, injury severity score; SAE, splenic artery embolization.
