*The no intervention group was not included in any of the significance testing.
†P values were used to examine differences between the open and endovascular repair groups, and were based on non-parametric Wilcoxon rank-sum tests or parametric two-sample t-tests for continuous variables and Fisher’s exact tests for categorical variables.
‡P values were used to examine differences between all three repair groups (endovascular, open, hybrid), and were based on non-parametric Kruskal-Wallis tests or parametric analysis of variance (ANOVA) tests for continuous variables and Fisher’s exact tests for categorical variables.
AIS, Abbreviated Injury Scale; GCS, Glasgow Coma Scale; HR, heart rate; ICU, intensive care unit; ISS, Injury Severity Score; LOS, length of stay; MTP, massive transfusion protocol; SBP, systolic blood pressure; TRISS, Trauma and Injury Severity Score.
