Results of statistical significances (p-values) comparing DTI parameters from WM tracts and GM between left (L) and right (R) hemicord, as well as between lateral CST and PC. There were no left and right differences in any of the WM or GM region (top three rows). A p-value of less than 0.0125 (with correction for multiple comparisons) was considered significant. Linear mixed-effects modeling was used to control for between-subject and nested slice level random effects, nSNR, translational motion, age and gender. Slightly larger diffusivity indices in PC than in lateral CST (supplementary data, Fig. 1) only manifest when controlling for slice level variance (last row).
