SWM test scores in MS relapse group, stable MS group, and healthy controls.

Test	MSr group (N-60)	MSs group (N-30)	CG (N-30)	ANOVA	Post hoc
SWM-TE	33.03 ± 19.94	23.40 ± 19.02	11.37 ± 11.08	F = 14.85; p < 0.001	CG < MSs,MSr# MSs = MSr**##
SWM-TE4	1.12 ± 1.94	0.90 ± 1.77	0.23 ± 0.57	F = 2.86; p = 0.061	CG = MSs = MSr*
SWM-TE6	8.58 ± 8.60	4.90 ± 6.31	1.93 ± 2.66	F = 9.53; p < 0.001	CG < MSr** CG = MSs MSs = MSr
SWM-TE8	23.18 ± 12.53	17.40 ± 12.35	9.13 ± 9.70	F = 14.17; p < 0.001	CG < MSs,MSr MSs = MSr*

MSr, relapse group; MSs, stable group; CG, control group; SWM, Spatial Working Memory; SWM-TE, total errors of SWM; SWM-TE4/6/8, total errors for 4, 6 or 8 boxes of SWM.

Low score denotes better cognition.

^*Bonferroni test was used for post hoc analysis.

^**Tamhane test was used for post hoc analysis.

^#CG < MSr indicates that the means of groups CG and MSr significantly differ.

^##MSs = MSr indicates that the means of groups MSs and MSr do not differ significantly.
