Fig. 3From: CSF total tau/α-synuclein ratio improved the diagnostic performance for Alzheimer’s disease as an indicator of tau phosphorylationConcordance between biomarkers in groups defined by clinical or amyloid-PET. a–d groups classified by clinical. e–h groups classified by amyloid-PET. Scatter plot: a, e Aβ42 versus T-tau, b, f Aβ42 versus T-tau/α-syn, c, g Aβ42/P-tau181 versus T-tau, and d, h Aβ42/P-tau181 versus T-tau/α-syn. Vertical and horizontal dashed lines indicate the cutoff of each biomarkerBack to article page
