Concentrations and diagnostic performance of serum p-tau231 and p-tau181 in biomarker-positive AD vs. biomarker-negative controls in cohort 3. A, B Serum p-tau231 and p-tau181 levels respectively in controls and AD, expressed in pg/ml. C Area under the curve (AUC) performances of serum p-tau231 and p-tau181 to separate AD from age-matched controls
