Abbreviations: OH, orthostatic hypotension; SE, standard error.
a
Estimated using generalized estimating equations. Total measurements differ from Supplemental Table 1 because supine measurements were used to calculate postural changes in BP used in determining OH.
b
Only 488 participants, total of 5110 measurements.
c
For the mean estimates there were 491 participants with 1730 measurements for blood pressure and 488 participants and 1703 measurements for heart rate.
