Overall demographics, clinical outcomes, mechanism of injury, blood and blood components, comorbidities, and disposition of the BD < 4 () and BD 4 () subgroups. Values are expressed as mean ± SEM. Mann–Whitney U test, Fisher exact test, or Chi-square were used as appropriate with statistical significance set at .
