Fig. 4 — Correlations between changes in clinical scale scores and brain functional connectivity. (A) During the treatment period, there was a correlation between the change in the K-ARS scores and FC from the PCC seed to the right superior frontal gyrus in the ADHD+SOM group (r = −0.67, p < 0.01). (B) During the treatment period, there was a correlation between the change in the K-ARS and FC from the PCC seed to the right superior frontal gyrus in the ADHD-SOM group (r = −0.60, p = 0.02). (C) During the treatment period, there was a correlation between the change in the SCL-90R-SOM and FC from the PCC seed to the right superior frontal gyrus in the ADHD+SOM group (r = −0.61, p = 0.02). (D) During the treatment period, there was a correlation between the change in the scores of the SCL-90R-SOM and FC from the PCC seed to the right superior frontal gyrus in the ADHD-SOM group (r = −0.09, p = 0.74). ADHD+SOM, adolescents with attention deficit hyperactivity disorder (ADHD) with somatic symptoms; ADHD-SOM, adolescents with ADHD without somatic symptoms; K-ARS, Korean version of Dupaul’s ADHD rating scale; SCL-90R-SOM, symptom checklist-90-revised-somatization subscales; FC Rt. SFG, functional connectivity (FC) from the posterior cingulate cortex (PCC) seed to the right superior frontal gyrus.
