White matter integrity is associated with cognition and amyloid burden in older adult Koreans along the Alzheimer’s disease continuum

Table 4 Partial correlations of WM integrity metrics with amyloid deposition. Pearson’s partial correlations between average [¹¹C]PiB-PET SUVR in the medial temporal lobe (MTL) and DTI indices in the left and right CBH. Significance is determined at the Bonferroni-adjusted p-value of 0.00625 and all partial correlations in this table are controlled for age, sex, and APOE ε4 allele positivity. All associations indicated by asterisk (*) were significant (p < 0.001) with small to medium effect sizes
