Study participants. We included 94 participants in the study. Table 1 summarizes demographic characteristics and biomarker results in the overall study population and according to the visual interpretation of amyloid PET scans as amyloid-positive (63%) or amyloid- negative (37%). There were no differences in age or sex between both groups. As expected, the amyloid-positive group had a higher proportion of APOEε4 carriers compared to the amyloid-negative group (52% and 20%, respectively; p=0.004).
