Regression analysis in the amyloid-positive and the amyloid-negative subgroups. 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 entorhinal thickness. Correlational plots have been divided based upon amyloid status (CL cutoff = 23.4): n = 152 amyloid-negatives, n = 27 amyloid-positives; Pearson Rho and the corresponding uncorrected P value are plotted per amyloid group. Association illustrated as least squares regression line ±95% confidence interval. Abbreviations: AVLT, Rey Auditory Verbal Learning Test; BSRT TR, Buschke Selective Reminding Test total retention
