Fig. 2: Correlation between plasma biomarkers with cerebrospinal fluid (CSF) counterparts.
From: Plasma biomarkers predict Alzheimer’s disease before clinical onset in Chinese cohorts
The concentrations of Aβ42 (a), Aβ40 (b), t-tau (c), p-tau181 (d), and NfL (e) in plasma are correlated with their counterparts in CSF in cohort 1 at follow-up. Adjusted R2, β, and uncorrected P values from two-sided linear regression are shown separately in each panel. Blue circles indicate controls while orange circles indicate participants with AD. Solid lines indicate the correlation. n = 123 (control), 126 (AD). Aβ amyloid-β, AD Alzheimer’s disease, NfL neurofilament light chain, p-tau181 phosphorylated tau, t-tau total tau. Source data are provided as a Source Data file.
