Notes: Aβ 40 = plasma beta amyloid 40; Aβ 42 = plasma beta amyloid 42; MA = Mexican American; NfL = plasma neurofilament light chain; NHW = non-Hispanic White; total tau = plasma total tau. All models are adjusted for age, gender, and education: (β, p-value) [95% confidence interval]. All p values < .05 are bolded.
