Standardized scores for educational outcomes were the dependent variables, and the DTI parameters (FA, Fractional Anisotropy; MD, Mean Diffusivity) for the stated regions of interest, age and hearing status (i.e., unilateral hearing loss, UHL) were entered in the models as predictors. FA, Fractional Anisotropy; MD, Mean Diffusivity.
