  1. Summarized retinal vessel calibres and software generated vessel reactivity parameters
  2. Data presented as mean (SD) or median (lower quartile-upper quartile)
  3. Au arbitrary units, CRAE central retinal artery equivalent, CRVE central retinal vein equivalent, AVR arterio-venous ratio, A max IMEDOS software generated arterial maximum dilation to flicker, A min IMEDOS software generated arterial maximum constriction following flicker, A peak IMEDOS software generated arterial dilation amplitude, V max IMEDOS software generated venous maximum dilation to flicker
  4. p values by analysis of variance or the Kruskal–Wallis test as distribution demands
