Linear regression between florbetaben(18F) (FBB)-positron emission tomography (PET) global SUVR and Aβ total plasma (TP)42/40 plasma ratio in SCD subjects. Inverse association between Aβ TP42/40 plasma ratio and FBB-PET scan. Experimental cut-off point of Aβ plasma ratio TP42/40 established at 0.08 to reduce the prescreening number of Aβ FBB-PET scans to 52.8%. CI confidence interval, NPV negative predictive value, PPV positive predictive value
