Predictors of episodic memory decline. A more positive value for BSRT TR slope corresponds to less decline. Correlation between episodic memory slope and a age at baseline, b Rey Auditory Verbal Learning Test (AVLT) total learning at baseline, c VBM hippocampal grey matter volume and d precuneus SUVR as index for amyloid load. Correlation between weighted composite episodic memory factor slope and e age at baseline, f episodic memory factor score at baseline, g VBM hippocampal grey matter volume and h precuneus SUVR. Data points have been colour-coded based upon amyloid status (CL cutoff = 23.4): n = 152 amyloid-negatives (black), n = 28 amyloid-positives (blue). Note that for all variables the sample size is n = 180, except for hippocampal volumes: n = 179; Significant associations are plotted as least squares regression line ±95% confidence interval; Pearson rho.
