Note.

*

Sensitivity analyses excluded 8 participants with cardiovascular disease or atrial fibrillation. Models were adjusted for age, race/ethnicity, education, Framingham Stroke Risk Profile (FSRP) minus age, and cognitive diagnosis. CI=confidence interval. CSF=cerebrospinal fluid. CVD=cardiovascular disease. MCI=mild cognitive impairment. NC=normal cognition.FIGURES
