CSF biomarker interactions with telomere length on longitudinal executive function. Telomere length interacts with both CSF Aβ-42 and tau on change in executive function, such that telomere length is associated with decline in executive function only in biomarker-positive individuals. Annual change in executive function is presented on the y-axis, and telomere length along on the x-axis. Points and lines are colored by CSF amyloid or tau status, with biomarker-positive individuals in red and biomarker-negative individuals in black.
