Scatterplots and association curves of age with the California Verbal Learning Test short form, 2nd Edition (CVLT); proportion (percent) retained between learning trials and 10-minute “long” delay recall. Cross-sectional population range of age (64 to 95 years) on the X-axis. Y-axis features include percent retained between learning trials and long delay free recall (A); best performance between trials 3 and 4 (B); and long delay free-recall score (C). Stratification by apolipoprotein E (APOE) ε4 carrier status, with non-carriers in (light) blue and carriers in (dark) purple (or dark navy, dark green). Association lines using fractional polynomial fit (blue, purple) with 95% confidence interval (gray)
