Age-corrected mean FA for patient and control groups by different evaluation strategies

	Group	Evaluation Strategy
	Group	A	B	C	D
FA_mean	Patients (n = 10)	0.644 ± 0.049	0.728 ± 0.075	0.693 ± 0.076	0.672 ± 0.064
(Age corrected) ± SD	Control subjects (n = 20)	0.694 ± 0.045	0.770 ± 0.048	0.732 ± 0.020	0.691 ± 0.045
Significance of group difference		P = .001	P = .011	P = .004	P = .162
DSR		1.12	0.86	1.96	0.43

Note:—FA indicates fractional anisotropy; FA_mean, mean value of FA measurements of the respective variability assessment; DSR, difference vs SD ratio.
