The mean of DKI measures for the 2 groups, based on the median EDSS score^a

Measure	Location	Group 1 (n = 11)	Group 2 (n = 8)	P Value^b
FA	WC	0.54 ± 0.04	0.49 ± 0.06	.002
	GM	0.74 ± 0.19	0.65 ± 0.22	.01
	WM	0.53 ± 0.09	0.50 ± 0.09	.1
MD	WC	0.92 ± 0.09	0.95 ± 0.09	.001
	GM	0.70 ± 0.21	0.75 ± 0.23	.001
	WM	0.96 ± 0.15	1.03 ± 0.14	.5
MK	WC	1.07 ± 0.11	1.06 ± 0.10	.01
	GM	1.13 ± 0.13	1.10 ± 0.09	<.0001
	WM	1.09 ± 0.15	1.08 ± 0.14	.3

Note:—FA indicates fractional anisotropy; MD, mean diffusivity; WC, whole cord.
↵a Group 1: EDSS score ≤ 2.5; group 2: EDSS score ≥ 3.0.
↵b P values are from ANCOVA, comparing groups 1 and 2 in terms of the indicated DKI measure adjusted for age, sex, and disease duration.
