Fig. 1From: Diagnostic value of serum versus plasma phospho-tau for Alzheimer’s diseaseProfile of serum vs. plasma p-tau in paired samples from neurochemically defined biomarker-positive AD vs. biomarker-negative controls in cohort 1. A, B Boxplots of the concentrations of p-tau231 and p-tau181 in serum and plasma respectively. C The diagnostic performance of p-tau231 and p-tau181 in the paired plasma and serum samples, estimated using area under the curve (AUC) calculationsBack to article page
