Phi Coefficients Among High Risk Levels of Cardiovascular Biomarkers

(a) Ages 65+ in the NHANES 1999–2002 (N = 1,884)
	DBP	SBP	Pulse pressure	Resting pulse rate	Homocysteine
DBP		0.19***	−0.04+	−0.01	−0.01
SBP			0.48***	−0.02	0.03
Pulse pressure				−0.03	0.05+
Resting pulse rate					0.07*
Homocysteine

(b) Ages 70–79 in the MacArthur Study of Successful Aging [N=654 (N=363 for correlations to homocysteine)]
	DBP	SBP	Homocysteine
DBP		0.34***	0.09
SBP			−0.03
Homocysteine

DBP = diastolic blood pressure; SBP = systolic blood pressure.
