Figure 4.

Diffusion tensor imaging parameter maps (FA, RD) from whole‐brain and hypothesis‐based analyses involving associations with StimQ‐P₂ READ Bookreading Quantity subdomain scores. White matter voxels exhibiting significant association between Bookreading Quantity subdomain scores and increased fractional anisotropy and decreased radial diffusivity in whole‐brain (FA₁) and hypothesis‐based (FA₂, RD₂) analyses, controlling for age, gender and household income (P < .05, FWE‐corrected). Colour indicates the magnitude of association (ie the change in the DTI parameter for every point increase in StimQ‐P₂ READ score), controlling for child age and household income level (P < .05, FWE‐corrected)
