Impact of eGFR on Alzheimer's Disease Biomarkers: Univariate and Multivariable Analyses. Forest plot displaying the standardized β-estimates of eGFR across various Alzheimer's Disease biomarkers, including Aβ42, Aβ40, Aβ42/Aβ40 ratio, P-tau217, P-tau231, NfL, and GFAP. The estimates are shown for three models: univariate (black), adjusted for age and sex (orange), and adjusted for age, sex, and Aβ-PET status (blue). Negative β-estimates indicate an inverse relationship between eGFR and biomarker levels
