  1. Raw and adjusted macular VD means, standard deviation (SD) and standard error of the mean (SEM) are shown. Dispersion is shown as SEM.
  2. aa = after adjustment for the following factors: age, sex, years of education, hypertension, diabetes mellitus, heart disease and stroke, using multivariate regression analysis.
  3. ADD = probable Alzheimer´s disease dementia; CU = cognitively unimpaired; MCI-AD = mild cognitive impairment due to Alzheimer´s disease; MCI-Va = mild cognitive impairment due to cerebrovascular pathology; SD = standard deviation; SEM = standard error of the mean; VaD = vascular dementia; VD = vessel density.
  4. Statistical significance was set up at p < 0.05.
