Fig. 3From: Plasma amyloid-β oligomerization assay as a pre-screening test for amyloid statusReceiver operating characteristic (ROC) curves discriminate abnormal amyloid from normal amyloid subjects as defined by amyloid PET scan based on plasma Aβ oligomer levels (blue line), age and APOEe4 genotype (purple line), and a multivariate model including APOEe4 genotype, age, and plasma Aβ oligomer levels (yellow line)Back to article page
