A. Mean NT-proBNP level by quartile of cognitive function test performance. Means and error bars are expressed as the antilog of the transformed means and standard deviations, respectively. Cut-points for quartile of MMSE scores are: ≤27, 28, 29, and 30. Cut-points for Trails B are: ≤75, ≤100, ≤139, and >139. Cut-points for Category Fluency are: ≤15, ≤18, ≤21, and >21.

B. Percent of participants with poor performance on each cognitive function test, by quartile of NT-proBNP. Cut-points for quartiles of NT-proBNP are: ≤74.8 pg/mL, ≤175.1 pg/mL, ≤364.7 pg/mL, and >364.7 pg/mL.

MMSE = Mini Mental State Exam, Trails B = Trail-Making Test B.
