Predictor variables can be measured differently (eg, education is categorical [0–6, 7–9, and ≥10 years] in CAIDE but binary [<12 and ≥12 years] in BDSI). AgeCoDe=Study on Aging, Cognition and Dementia. ANU-ADRI=Australian National University Alzheimer's Disease Risk Index. BDRM=Rotterdam Study Basic Dementia Risk Model. BDSI=Brief Dementia Screening Indicator. CAIDE=Cardiovascular Risk Factors, Aging, and Dementia Risk Score.
