The x, y, z coordinates are the primary peak locations in the MNI space. Cluster size > 19 voxels in ANCOVA analysis, p < 0.05; Cluster size > 10 voxels in post hoc test, p < 0.05, TFCE-FWE corrected; L, left; R, right; B, bilateral; aMCI, amnestic mild cognitive impairment; SCD, subjective cognitive decline; HC, healthy control.
