The regression of functional connectivity on mFD was not significant for any of the 4 networks (p greater than 0.246). The regression of functional connectivity on education was not significant for any of the 4 networks (p greater than 0.294). Thus, none of the baseline variables mFD, education, or NU met the criteria for inclusion as a covariate in ANCOVA, due to lack of a significant relationship of these variables with functional connectivity in this sample [37].
