Note: The significance of the model is included as well as the contributions of each covariate within the model. The covariates included within the univariate ANCOVAs were age, sex, site, and vendor. This model includes fraction white matter (fWM) and the interaction term Group*fWM as a covariate. p‐values in bold were considered statistically significant at p < .05.
