Table 3 Regression models for TD group describing processing speed scores’ dependence on faxon and Daxon in the mid and posterior segments, controlling for the number of voxels (NumVox) in that segment. Adjusted R2 (i.e., R2 adjusted for the number of predictors in the model) and uncorrected p values are reported
