Figure 2.

Interaction effects (group × time) for gFCD (cluster size‐corrected, p _FWE < .05). (a) There were significant interaction effects (group × time) on gFCD in the VMPFC, right DLPFC and right insula. (b) SG group after surgery had decreased gFCD in those brain regions. Ctr group did not show significant gFCD changes. (c) Correlation analysis between behavioral measurements and gFCD. The error bars indicate the standard error. Abbreviation: FCD, functional connectivity mapping; VMPFC, ventromedial prefrontal cortex; DLPFC_R, right dorsolateral prefrontal cortex; INS_R, right insula; BMI, body mass index; YFAS, Yale food addiction scale [Color figure can be viewed at http://wileyonlinelibrary.com]
