There was no effect of age (F[39]=1.7; p=0.203) or gender (F[39]=0.001; p=0.977) in the comparison of central FA between BDE and CONT, therefore these factors were not entered in the model.
#
Mauchly's test of non-sphericity was significant, as such Greenhouse-Geisser corrections were used, corrected degrees of freedom=(2, 68).
