Pairwise comparisons are conducted between CTL, SYM, and concussed athletes at medical clearance to return to play (RTP). Results are reported as mean and repeated‐measures bootstrapped 95% confidence interval, along with empirical p‐values. Diffusivity values AD and RD are reported in units of mm²/s, while all other measures are dimensionless and range from 0 to 1.
