Table 2. Autonomic Function Data of the Study Patients
Values are mean ± SD.
DAN = diabetic autonomic neuropathy; E/I ratio = the ratio of the maximum RR interval during expiration to the minimum RR during inspiration; DABP = diastolic arterial blood pressure; HR = heart rate.
* Only 15 and 10 patients in older and DAN-positive groups, respectively, were able to perform these tests.
†P < 0.05, all controls versus DAN-positive group.
‡P < 0.05, young group versus DAN-positive group.
§P < 0.05, older group versus DAN-positive group.
∥P < 0.05, young group versus older group.
#P < 0.05, DAN-negative group versus DAN-positive group.
