Shown are demographic as well as preclinical and clinical characteristics in a direct comparison of the groups. Abbreviations: CT: computed tomography, SD: standard deviation. Since blood sampling is not standard practice in every patient, blood alcohol concentrations are not available for the comparison group. Student’s t-test was used to compare the mean age values. For the remaining categorical variables, the chi-square test was used. * p < 0.05.
