T₂, T₁, ADC, and FA distributions in mTBI (n = 19) and controls (n = 18) (CTL) at timepoint 1. As in the statistical analysis, the boxplots exclude the three non-age-matched patients. Note that T₁ and T₂ in mTBI did not differ from controls for any region. Compared to controls, FA in patients was lower in the frontal white matter (Mann–Whitney test, p < 0.05). The middle line in the boxes depicts the median value, and the boxes’ top and bottom edges the 25^th and 75^th percentiles of the data, respectively. The whiskers extend to the most extreme data points not considering outliers (95% of data), which are depicted by a plus sign.
