Odds ratio for 30-day mortality associated with whole-body computed tomography (CT) by several adjustment methods. C index statistic corresponding to the area under the receiver operating characteristic (ROC) curve *Multivariate logistic regression adjusted for pre-CT (age, hemoglobin, prothrombin ratio, ventilation, Glasgow Coma Scale, fluid loading, center, and pre-hospital cardiac arrest) and post-CT confounders (number of packed red blood cells in the first 24 hours and catecholamine administration in the first 24 hours). ^†Multivariate logistic regression adjusted for post-CT confounders (number of packed red blood cells in the first 24 hours and catecholamine administration in the first 24 hours). CI, confidence interval; OR, odds ratio.
