a trend toward significancep = 0.05
In the unadjusted model, higher MDS-OAβ levels were significantly associated with a lower TBR in the frontal (β = −0.04, p = 0.02), central (β = −0.06, p = 0.02), and temporal lobes (β = −0.06, p = 0.01), with a trend toward significance in the parietal lobe (β = −0.05, p = 0.05).
