Correlation between VAS scores, BMI, and FC of the right CN. BMI is positively correlated with FC values between the right CN and the (A) Lingual_R (according to the AAL atlas); (B) Lingual_L; (C) Calcarine_R; and (D) Calcarine_L. VAS scores are negatively correlated with FC values between the right CN and the (E) Calcarine_L and (F) Lingual_R. Note: The results shown are from two-tailed tests (p < 0.05) for the significance of Pearson’s correlation coefficient. AAL, automated anatomical labeling; VAS, visual analogue scale; BMI, body mass index; L, left; R, right; FC, functional connectivity; CN, caudate nucleus.
