Additional file 4 of Cerebrospinal fluid A beta 1–40 peptides increase in Alzheimer’s disease and are highly correlated with phospho-tau in control individuals

Additional file 4 : Sup-Figure 2. ROC curves of Aβ40, Aβ42 and Aβ42/40 ROC curves of Aβ40, Aβ42 and Aβ42/40 for the detection of AD in different cohorts. AUC of Aβ40 had lower values than the other biomarkers (Mtp-1 0.686 (0.638 to 0.731); Mtp-2 0.751 (0.711 to 0.788); Paris 0,679 (0.641 to 0.716); SPIN-Barcelona 0.730 (0.667 to 0,787)).
