Figure 4. PiB status only has an effect on hypometabolism associated with inferior temporal tau, not with entorhinal tau.
Scatterplots of FTP (tau-PET) against FDG SUVR signals in selected ROIs. P-values in the right-upper corners indicate the significance of the interaction effect between FTP and PiB status on FDG (see Table 2 box 3.A). Dots are categorized by PiB status (blue: low-PiB (n=57), red: high-PiB (n=33)). Entorhinal and inferior temporal FTP have different impact on posterior cingulate FDG in low-PiB, but similar in high-PiB participants.
