The green table color indicates a rejection of the null hypothesis, whereas the red table coloring indicates that there is not enough evidence to reject the null hypothesis. The χ2-values from the Kruskal-Wallis ANOVA test and p-values from the Wilcoxon rank sum test for the different subgroups are given as table entries. AIS, abbreviated injury scale; AP, alkaline phosphatase; APACHE, acute physiology and chronic health evaluation; CRP, C-reactive protein; GCS, glasgow coma scale; GLDH, glutamate dehydrogenase; GGT, gamma glutamyl transpeptidase; GOT, glutamic oxaloacetic transaminase; GPT, glutamic pyruvic transaminase; Hb, hemoglobin; IL, interleukin; INR, international normalized ratio; ISS, injury severity score; K, potassium; Na, sodium; PT, prothrombin time; PTT, partial thromboplastin time; SOFA, sequential organ failure assessment.
