Survey linear regression models were used to examine associations between CKD status (estimated glomerular filtration rate [eGFR] < 60 ml/min/1.73m2 or urine albumin-creatinine ratio [uACR]) > = 30 mg/g) and the plasma ATN biomarkers (β-amyloid 42/40 ratio [Aβ42/40 ratio], phosphorylated-tau181 [p-Tau181], neurofilament light [NfL], and glial fibrillary associated protein [GFAP]), independently. This evidence concerns the gene GFAP and chronic kidney disease.
