Figure 2. Relationship between UPSIT score and 18F-MK-620 PET.
Lower UPSIT scores were associated with greater 18F-MK-6240 binding when all participants included in medial temporal cortex (r = −0.59, p < 0.01) and hippocampus (r = −0.60, p < 0.01). Correlations remained when only amyloid-positive participants were included (medial temporal cortex: r = −0.52, p = 0.02; hippocampus: r = −0.53, p = 0.02) but not when only amyloid-negative participants were included. Data corrected for age and sex.
