Table 4.

Results of proportional odds models showing relationship between quartile of unipedal stance time and mean blood flow velocity by TCD.

Mean Blood Flow Velocity (MBFV),(cm/sec)	OR for being in the next higher quartile of Unipedal stance time¹
	Odds ratio	95% confidence interval	P value
ACA-MBFV	1.03	0.98–1.07	0.209
MCA-MBFV	1.03	0.99–1.06	0.118
BA-MBFV	1.05	1.01–1.10	0.022
VA-MBFV	1.07	1.01–1.14	0.019

MBFV=mean flow velocity, ACA=anterior cerebral artery, MCA=middle cerebral artery, BA=Basilar artery, VA=vertebral artery. Significant results are bolded in the table.

Adjusted for age, sex, race (white-ref.), education, diabetes, hypertension, stroke, heart disease, and arthritis.
