Fig. 2:

(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 both age modified Japanese Orthopedic Association (mJOA) score. (B) ROI-to-ROI FC association with NDI for CS patients only, after controlling for both age and mJOA. 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.
