A-F, Model expected values of cognition over time for representative participants (female participants aged 85 years with 15 years of education) with 25th (orange), 50th (dark gray), and 75th (blue) percentiles of β-amyloid level in global cognition (A), episodic memory (B), semantic memory (C), working memory (D), processing speed (E), and visuospatial ability (F). The expected values over time are calculated using point estimates of both intercept and slope as derived from the linear mixed models.
