  1. BP Blood pressure, NAION nonarteritic anterior ischemic optic neuropathy
  2. Statistical significance tested by ANOVA for normal distributions and Kruskal–Wallis tests for nonnormal distributions; all comparisons were corrected with the post hoc test. The categorical data were analyzed using the Fisher’s exact test of chi-square tests
  3. aNonnormally distributed variables, represented by median (interquartile range)
  4. bNormally distributed variables, represented by mean (±standard deviation)
