Fig. 2: Association between salivary mtDNA levels and ¹⁸F-Florbetaben (FBB)-PET binding to Aβ deposits in the neocortex.

(A) Significant results projected onto the cortical surface. (B) The scatter plot shows the relationship between salivary mtDNA levels and the peak vertex of cortical FBB binding, adjusted for age and sex. L: left.
