Table 3.

The mean, standard deviation (SD), median, and interquartile range (IQR) of the within-subject change in MRI measures among mTBI patients. The change was computed for each subject as the value at timepoint 2 minus the value at timepoint 1. Only patients providing data at both times were included in the computations. p-values are from the matched-pair Wilcoxon signed-rank test (WSRT) assessing whether the change was different from zero. Only measures with p < 0.05 are presented
