MAPT and dementia: AUC for the Amyloid-β, P-tau, T-tau, P-tau/Aβ42, and T-tau/Aβ42 were 0.334 (0.296–0.390, p < 0.001), 0.644 (0.594–0.695, p < 0.001), 0.607 (0.556–0.657, p < 0.001), 0.706 (0.655–0.756, p < 0.001) and 0.756 (0.714–0.799, p < 0.001), respectively, indicate a moderate accuracy to predict dementia.
