3 clusters revealed by Binary DC in aICAO patients compared to HCs, including Precuneus_L (Contra), Frontal_Inf_L (Contra), and Cuneus_R (Ipsi). Areas with decreased Binary DC relative to controls are displayed in blue, and areas with increased Binary DC are displayed in red. Color bars represent T values. The result was corrected using the GRF correction with the voxel level p < 0.001 and cluster level p < 0.05. DC, degree centrality; aICAO, asymptomatic internal carotid artery occlusion; HC, healthy control; Frontal_Inf_L, left inferior frontal gyrus; Precuneus_L, left precuneus; Cuneus_R, right cuneus. Ipsi, ipsilateral (occlusion side); Contra, contralateral (opposite to occlusion side). Gaussian random field, GRF
