The statistical threshold was set at the voxel level with p < 0.01 for multiple comparisons using Gaussian random-field theory (two-tailed, voxel-level P < 0.01, GRF correction, cluster-level P < 0.05). dALFF, dynamic amplitude of low-frequency fluctuation; BA, Brodmann area; DR, diabetic retinopathy; HC, health control; MNI, Montreal Neurological Institute; GRF, Gaussian random field; L, left; R, right.
