	Hemisphere	FA	p Value	Tract volume	p Value
Patient group	Right	0.36 (0.04, 0.36)	0.015*	69.08 (30.33, 72.00)	0.000*
	Left	0.35 (0.04, 0.36)		78.86 (28.80, 80.50)

Values represent mean (±SD, median value).

*p<0.05.

FA, fractional anisotropy; p, an independent t test for determination of variances in FA and tract volume between the patient and control groups.
