The DMN FC differences among the three groups. According to the ANCOVA, the 11 brain regions with significant differences were mainly located in the frontal cortex, parietal cortex, and cingulate cortex. The thresholds were set at a corrected P < 0.05, determined by Monte Carlo simulation for multiple comparisons (voxelwise P < 0.01, FWHM = 6 mm, cluster size > 999 mm3).
