Table 1. Comparisons between demographic characteristics and MMI scores of participants involved in VBM analyses and functional connectivity analyses.
Figure 1. VBM regression analyses revealed that MMI scores were significantly associated with gray matter density in the ACC (t(70) = 5.16, P FWE-corrected , 0.05, Cluster size = 158 voxels x 1.5 3 = 533 mm 3 ; peak MNI coordinate: x = 12, y = 41, z = 3)
Figure 2. Regression analyses revealed that connectivity between the ACC ROI and the Precuneus (intersection of blue lines) was negatively associated with MMI scores (Precuneus; t(40) = 5.22, P FWE-uncorrected ,0.001, Cluster size = 159 mm 3 ; Peak MNI coo
