Based on three sets of ridge regression models (model 1: CSF p‐tau181, model 2: tau PET SUVR in the temporal meta‐ROI, model 3: CSF and PET combined) for each AD‐related feature, we examined the possible differential associations for either tau PET or CSF p‐tau181 to other AD‐related features (Fig 3A). The gene discussed is MAPT; the disease is Alzheimer disease.
