ROC curves of a individual CSF biomarkers and b biomarker ratios to predict Aβ-PET status. AUC statistics are presented for each biomarker. Abbreviations: , β-amyloid; Aβ42, β-amyloid (1–42); Aβ42/Aβ40, β-amyloid (1–42)/β-amyloid (1–40) ratio; AUC, area under the curve; CSF, cerebrospinal fluid; PET, positron emission tomography; pTau, phosphorylated tau (181P); pTau/Aβ42, phosphorylated tau (181P)/β-amyloid (1–42) ratio; tTau, total tau; tTau/Aβ42, total tau/β-amyloid (1–42) ratio
