Midlife cardiovascular characteristics among demented, MCI, and control subjects

Characteristic% Demented subjects, n =57% Subjects with MCI, n = 82% Control subjects, n = 1270p ValueTest for linear trend
χ2 Test was used.
* Low indicates systolic blood pressure <160 mmHg and cholesterol <6.5 mmol/L; single risk factor, systolic blood pressure ≥160 mmHg or cholesterol ≥6.5 mmol/L; combined, systolic blood pressure ≥160 mmHg and cholesterol ≥6.5 mmol/L.
p Value for between-group difference.
