Representative cut-off values of contact factors and CSF Aβ1–42/contact factor ratios. Cut-off values of Aβ1–42 (a), FXIIa (b), and CSF Aβ1–42/FXIIa ratio (c) capable of discriminating prodromal AD from normal. Cut-off values of Aβ1–42 (d), FXIIa (e), and CSF Aβ1–42/FXIIa ratio (f). ROC curves are shown for each marker, in which arrows indicate cut-off values capable of distinguishing P-AD and AD-D groups from NR
