  1. 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).
  2. N number of patients, ED erectile dysfunction, AVR artery–vein ratio, CRAE central retinal artery equivalent, CRVE central retinal vein equivalent.
