Fig. 2. Whole brain voxel-wise correlation analyses were used to identify the associations between FCS and Edinburgh Postnatal Depression Scale (EPDS) and Beck’s Anxiety Inventory (BAI) scores.

A There is a significant positive correlation between FCS in paracentral lobule (ParaCL), and significant negative correlation between FCS in right cerebellem posterior lobe (CPL), and EPDS, respectively. B There is also a significant negative correlation between FCS in right CPL and BAI. C Post-hoc two sample t-tests showed that FCS was significantly lower in right CPL in both PPD and PPD-A patients compared to HPW. There was no significant difference in FCS between PPD and PPD-A patients in these or in any other brain regions.
