Figure 2. Longitudinal CSF t-tau and p-tau slopes by baseline CSF Aβ1–42 as stratified by APOEε4 status.
The y-axis represents slopes of CSF tau change in pg/mL per year (extracted from linear mixed models), while the x-axis represents baseline CSF Aβ1–42. The colors represent: red = APOEε4 carriers and blue = APOEε4 non-carriers.
