The multiple comparison correction for ALFF was used by the FWE correction with Monte Carlo simulation p < 0.05 and cluster size >107. The multiple comparison correction for ReHo was used by the FWE correction with Monte Carlo simulation p < 0.05 and cluster size >171.
ALFF, amplitude of low-frequency fluctuation; FEW, family-wise error; MNI, Montreal Neurological Institute; ReHo, regional homogeneity.
