Diabetic neuropathy results in vasomotor dysfunction of medium sized peripheral arteries

Table 2 Measurements of the brachial artery diameter before and after stimulation in the diabetic neuropathy and control groups

	Diabetic neuropathy (n = 41)	Control (n = 41)	P value1
Diameter before stimulation (mm)			0.107
mean ± SD	3.4 ± 0.6	3.6 ± 0.4
Median (25P-75P)	3.4 (3.1-3.8)	3.6 (3.2-4.0)
Min.-Max.	2.1-5.1	2.9-4.6
Diameter after stimulation (mm)			0.055
mean ± SD	3.6 ± 0.4	3.4 ± 0.5
Median (25P-75P)	3.6 (3.2-4.0)	3.4 (3.1-3.8)
Min.-Max.	2.9-4.6	2.3-4.7
P value2	0.072	0.046
