Relationship between tau PET measures and amyloid, cognition and volume. Tile plots show absolute correlation coefficients (rho) of Spearman rank correlations between tau PET measures and amyloid PET, Mini-Mental State Examination (MMSE), verbal episodic memory, bilateral hippocampal volume, entorhinal thickness and the mean correlation across columns. Correlations were calculated across old controls, MCI and AD patients within each sample. A. BACS/UCSF subjects. B. ADNI participants. Verbal recall was measured as percentage of correctly recalled words in the California Verbal Learning Test (CVLT) or Rey Auditory Verbal Learning Test (RAVLT).
