Note. Multiple regression models predicting cluster-FA in the left and right CTC from spelling accuracy scores and RAN scores. Cluster-FA refers to the mean FA across nodes 3–9 (see Figure 5). RAN scores are the average scaled scores of RAN Letters and RAN Digits. FA = fractional anisotropy, CTC = cerebello-thalamo-cortical tract, RAN = rapid automatized naming, B = unstandardized coefficient, SE = standard error, β = standardized coefficient, VIF = variance inflation factor.
