Age of participants indicates the mean age of participants at the start of the study. P-values are based on the results of two-tailed independent-samples t-tests for age and education and a chi-squares test for gender proportions. Abbreviations are as follows: GCSadmit = Glasgow Coma Scale score at hospital admission, GCS24 = Glasgow Coma Scale score 24 h post-injury, 15 h = Number of hours before patient reached a GCS score of 15, DAI = Diffuse axonal injury, CC = corpus callosum, T = Patient was intubated at the time of GCS assessment.
