140 Chapter 6 Figure 1. Neuropsychological test performance over time Spaghetti plots showing individual neuropsychological trajectories on two neuropsychological tests: Rey auditory verbal learning task delayed recall (A and C) and mini mental state examination (B and D). For visualization, the sample was divided into tertiles. Separate lines represent the unadjusted mean trajectory for each R1 tertile separately (A and B, based on baseline R1 values) and for each BPND tertile separately (C and D, based on baseline BPND values). Figures represent raw test scores.
