Fig. 1.

Trajectories of white matter development differed in dysfluent inaccurate, dysfluent accurate, and non-impaired readers in several brain regions (A–F). Solid lines represent significant relationships, while dotted lines represent non-significant fits; each group is shown in a different colour. The figures in the centre show the average fractional anisotropy map with the tract-based spatial statistics (TBSS) skeleton overlaid in green. Regions of interest that had significant group differences in trajectories are shown in colours.
