Cells show p-values based on a mixed linear model predicting session-to-session changes in the Reading Skill composite, Woodcock–Johnson Basic Reading (WJ-BRS), TOWRE index, and Woodcock–Johnson Reading Fluency (WJ-RF) from changes in mean diffusivity (MD) at each time point during the intervention. Pearson correlations between mean-centered MD and mean-centered reading score are provided as an index of effect size. Tracts that predict changes in readings scores at a Bonferroni-corrected p < 0.05 are highlighted in bold italic
