a–i Concordance correlation plots per biomarker. Black points represent data from positron emission tomography (PET)-Aβ− participants; grey points represent data from PET-Aβ+ participants. Round points represent those participants who were cognitively normal (CN); square points represent those participants with mild cognitive impairment (MCI); triangular points represent those participants with Alzheimer’s disease (AD). The solid black line represents the concordance correlation (CC) between gravity and aspiration extraction methods. Aβ; amyloid beta, BACE1; beta-secretase 1
