Standardized ß coefficients (significant in bold) from multiple regression analysis with gray matter density as the dependent variable and either CSF p-tau and/or [18F]flortaucipir BPND as predictors using separate analyses

Model 1 = Either CSF p-tau or entorhinal/limbic/neocortical [18F]flortaucipir BPND was used as a predictor. Effects adjusted for age, sex, intracranial volume, and time lag between MRI and LP or [18F]flortaucipir PET

Model 2 = CSF p-tau + neocortical [18F]flortaucipir BPND or entorhinal/limbic/neocortical [18F]flortaucipir BPND + CSF p-tau were used as predictors. Effects adjusted as model 1
