a–d ROC curves of Aβ42/40 and other plasma biomarkers. The parsimonious model consists of plasma Aβ42/40, p-tau181, and GFAP. * denotes p < 0.05, ** denotes p < 0.01, *** denotes p < 0.001. Abbreviations: ROC = receiver operating characteristic; Aβ42/40 = amyloid β 42/40 ratio; p-tau181 = tau protein phosphorylated at residue 181; GFAP = glial fibrillary acidic protein; NfL = neurofilament light; HC = healthy control; MCI = mild cognitive impairment
