Table 4:

Regions showing significant differences in gray matter density between HC and CLBP voxel-wise (corrected for multiple comparisons). Region descriptions are based on AAL3 atlas. The effect column describes the direction of difference. The cluster size and maximum t-value (representing the independent t-test) for the clusters as well as the location of the maximum are reported. Note that there are three significant clusters, however a cluster can have multiple labels, which are indented.

Description	Effect	Cluster Size (# Voxels)	t-value max	MNI coordinate (x, y, z)

Left Cerebellum VIII	HC > CLBP	499	4	−32, −54, −58
Left Cerebellum VIIb	HC > CLBP	94	4.2	−34, −68, −50
Left Cuneus	HC < CLBP	85	−4.8	−2, −90, 38
Left Superior Occipital	HC < CLBP	79	−5.6	−10, −86, 46
