Prognostic power of plasma markers in predicting cognitive decline based on longitudinal FAST assessments. All participants included in the analysis had baseline FAST score as 3. Scatter plots between year-3 FAST score and plasma markers are shown for GFAP ((a)), ptau-181 ((b)), and NfL ((c)). Blue circles indicate amyloid negative participants and red dots indicate amyloid positive participants. d Comparisons of baseline plasma concentrations of GFAP, ptau-181, and NfL between progressors (year-3 FAST > 3) and non-progressors (year-3 FAST ≤ 3). The plasma marker levels were adjusted for age, sex, and education
