Scatter plots demonstrating correlations between the right daMCC-pACC effective connectivity values and depression (MADRS scores), OCD (Y-BOCS scores) and anxiety (HAMA scores) symptom severity in OCD participants. Note that the right daMCC-pACC effective connectivity is specifically, significantly correlated with depression (a) but not with OCD (b) or anxiety (c) symptom severity. daMCC, dorsal anterior midcingulate cortex; pACC, pregenual anterior cingulate cortex; OCD, obsessive-compulsive disorder; MADRS, Montgomery-Åsberg Depression Rating Scale; Y-BOCS, Yale-Brown Obsessive-Compulsive Scale; HAMA, Hamilton Anxiety Scale.
