Fig. 1:

(A) ROI-to-ROI functional connectivity (FC) association with Neck Disability Index (NDI) for both patients with cervical spondylosis (CS) and healthy control (HC) volunteers after controlling for age (B) ROI-to-ROI FC association with NDI for patients with CS only, after by controlling for age. Colors denote value of the T-statistic, yellow-red represents positive association (increasing FC with increased neck disability), light blue-blue denotes negative association (increasing FC with decreasing neck disability). Position of ROIs displayed on mid-axial slices. PreCG = Precentral Gyrus; PostCG = Postcentral Gyrus; SFG = Superior Frontal Gyrus; SMA = Supplementary Motor Area; r = Right Hemisphere; l = Left Hemisphere.
