Additional file 15. Changes in FA value in children aged over 3 years/ Legends: In the subgroup analysis classified by median ages of four groups - younger aged subgroups (aged below 3 years; n = 49, median age 2.28y; A: 12, B: 14, C: 10, D: 13) vs. older subgroup (aged over 3 years; n = 39, median age 4.12y; A: 10, B: 10, C: 10, D: 9). Primary outcome measures did not show any significant differences between four groups. FA change ratio in right anterior thalamic radiation (ATR) between baseline and 12 months after intervention are depicted in this figure. Group A showed significant difference of FA change ratio in ATRR compared with group D. *P < 0.05 by post-hoc analysis after Kruskal-Wallis test comparing the difference among 4 groups. Abbreviations: ATR: anterior thalamic radiation; FA, fraction anisotropy.
