FreeSurfer-defined regions in which the interaction of FHS-CVD and Aβ correlated significantly with regional tau deposition. Regions were averaged across left and right hemispheres. In all regions shown, combined higher FHS-CVD and elevated Aβ was associated higher tau burden. Color bars indicate the t-statistic for the association, adjusting for age, sex, APOE ε4 status, and the time interval between baseline and the tau PET scan. Regions shown are p < 0.05 corrected for multiple comparisons (FWE).
