Longitudinal data, significant changes in gray matter in patients with chronic pain due to primary hip osteoarthritis.

The changes are tabulated in terms of the brain region and the corresponding Brodmann’s area (BA). The x, y, z co-ordinates are according to the MNI atlas. Each location is the peak within a cluster (defined as the voxel with the highest T-score). (Patients with OA, not flipped) Increase = increase in gray matter scan I/scan II>scan III>scan IV. Decrease = decrease in gray matter scan I/scan II
