Table 3. Negative association between changes in ReHo and cortisol changes.
Unstandardized β of cortisol changes was calculated from linear regression of ReHo changes predicted by natural log transformed cortisol changes, adjusted for body-mass index (BMI). CI: Confidence interval; IFO: Anterior insula and adjacent frontal operculum; LH: Left Hippocampus; MNI: Montreal Neurological Institute; ReHo: Regional homogeneity; RH: Right hippocampus.
*Whole-brain corrected p < 0.05, determined by AlphaSim (voxel-level uncorrected p < 0.001, k > 13 voxels).
^A subthreshold effect was observed on the LH, of which the ReHo changes also negatively associated with cortisol changes. This suggested that the association between changes in ReHo of the LH and changes in cortisol alone was weak.
