Table 4. RD change in white matter tracts and working memory change.

		Spatial Span Backward		Digit Span Backward

Partial correlation between change in RD in specific white matter tracts and change in Spatial Span Backward scores, controlling for age, sex, interval and motion at both time points. ILF = Inferior longitudinal fasciculus, IFOF = Inferior fronto-occipital fasciculus, UF = Uncinate fasciculus and FMaj = Forceps major. Numbers in bold signify Bonferroni-corrected significance level p < .05.
