A: averaged ± SE RR interval for able-bodied subjects (AB; n = 11), diabetics without neuropathy (D0; n = 6), diabetics with possible neuropathy (D1; n = 5), and diabetics with definite neuropathy (D2; n = 8) in response to HUT. All groups decreased RR interval during HUT. △Significantly different from control for the same group. ●Significantly different from AB at the same time segment. *Significantly different from D0 at the same time segment. B1: averaged ± SE systolic blood pressure (SBP) for AB, D0, D1, and D2 in response to HUT. AB tended to increase SBP in response to HUT while D2 tended to decrease SBP in the first 3 min of tilt and recover during tilt 3–7 and 7–12 min. B2: changes of SBP from supine control to the first 3 min of tilt. The changes of SBP were significantly different (●) between AB and D2.
