Rho- and p-values were estimated from the Spearman's rank partial correlation analyses, adjusted for age and APOE ε4 status. Global and regional amyloid-β load were not corrected for partial volume effects. P-values ≤ 0.05 are indicated in bold. Amyloid-β, amyloid-beta; APOE ε4, apolipoprotein E ε4; ECog-39, 39-item Everyday Cognition Scales; PSWQ, Penn State Worry Questionnaire; SUVR, standard uptake value ratio.
