The FC ratio was calculated by means of the quotient: post FC/pre FC. ANCOVA test, with sex as covariate, was calculated between groups with the corresponding average FC ratio. The accuracy score was obtained through a logistic regression analysis with the leave-one-out cross-validation procedure. MNI coordinates of the center of each ROI were calculated in the corresponding network. One sample t-test was calculated with the ratio value of each group per each significant link. rIPL/lIPL (right/left inferior parietal lobe). Pc (precuneus). FMC (frontal middle cortex). ACC (anterior cingulate cortex).
