Dynamic vessel analyzer parameters in patients and controls.

	ED (N = 35)	Controls (N = 30)	p value
Dynamic analysis
Arterial dilation (%)	1.88 ± 1.50	3.70 ± 1.56	< 0.0001
Arterial constriction (%)	− 0.56 ± 1.22	− 0.52 ± 1.54	0.430
Reaction amplitude (%)	2.40 ± 2.02	4.25 ± 2.20	0.023
Venous dilation (%)	2.79 ± 2.38	3.4 ± 2.96	0.241
Static analysis
AVR	0.98 ± 0.27	0.97 ± 0.21	0.127
CRAE	252.1 ± 47.4	221.3 ± 56.6	< 0.0001
CRVE	259.3 ± 40.1	229.7 ± 43.2	0.024

Values are compared using a one-way analysis of covariance (ANCOVA) with age, diabetes, hypercholesterolemia and systemic hypertension as covariates. Data are presented as mean ± SD (standard deviation).

N number of patients, ED erectile dysfunction, AVR artery–vein ratio, CRAE central retinal artery equivalent, CRVE central retinal vein equivalent.
