  1. RT, right; LT, left; CST, corticospinal tract; CTR, corticothalamic radiations; MD, mean diffusivity
  2. A two-sample t-test analysis was performed to compare the results of ROI-based data between the CP and control groups. p < 0.001 was applied to correct for multiple comparisons
  3. *Bold text denotes significant between group differences following multiple comparisons correction with a level of significance determined at p ≤ 0.001. Units for MD is 10–3 mm2/s whereas FA is dimensionless
