Fig. 2. Relationships between functional connectivity of the network components and pain catastrophizing. Associations between mean functional connectivity of the network components with (A) higher (components 1~2) or (B) lower (components 3~6) functional connectivity and PCS total scores were examined in patients with CRPS using linear regression. The solid lines indicate the line of best fit, and the dashed lines indicate the 95% confidence intervals. CRPS, complex regional pain syndrome; PCS, Pain Catastrophizing Scale.
