Abbreviations: ncDNA = nuclear DNA; mtDNA = mitochondrial DNA; WBC = white blood cell; ISS = injury severity score; APACHE II = acute physiology and chronic health evaluation II; DFR = distance from reference

aSpearman correlation coefficients (rho) were used to determine the relationships between variables. Corresponding p-values along with the number of patients upon which these correlations were derived are also listed.

bMaximum lactate was the greatest lactate (mmol/L) within 24 hours of injury.
