Tests used: t-test for two samples: age, SBP, ISS, sodium; Wilcoxon's two-sample test: AIS head, GCS; Wilcoxon's rank-sum test: hemorrhage volumes; chi-square: sex; Fisher's exact test: ASA. Bold italicized values are used to indicate significant findings (p < 0.05). Interquartile range (25th–75th percentile).
ASA, American Society of Anesthesiologists; SD, standard deviation; SBP, systolic blood pressure; ISS, Injury Severity Score; GCS, Glasgow Coma Scale; AIS, Abbreviated Injury Scale; TBI, traumatic brain injury.
