MAPT and dementia: The models including tau PET visual reads (AUC, 0.74; 95% CI, 0.68-0.79; P = .06), Aβ PET (Centiloids: AUC, 0.73; 95% CI, 0.68-0.79; P = .32; visual read: AUC, 0.72; 95% CI, 0.66-0.78; P = .42), or MRI (AD signature thickness: AUC, 0.74; 95% CI, 0.68-0.80; P = .26; MTA visual read: AUC, 0.73; 95% CI, 0.68-0.79; P = .32) did not provide a better prediction for conversion to all-cause dementia than the base model (Figure 1A).
