Apo E = Apolipoprotein E; Hyperlipidemia = total cholesterol >5 mmol/l or low-density lipoprotein cholesterol >3 mmol/l; Coronary heart disease = previous myocardial infarction or present angina pectoris; BMI = body mass index. The values are the regression coefficients for the 10-word test and TMT B (linear regression) and the odds ratio for the Clock Drawing Test (logistic regression).
