  1. Values represent mean (±standard deviation); ARAS Ascending reticular activating system, FA Fractional anisotropy, TV Tract volume; One-way ANOVA and the LSD post hoc test were used for comparison of diffusion tensor parameters
  2. *significant difference between the patient and control groups at the indicated p
  3. LSD test result: a < b
