  1. Patients are grouped based on the use of beta-blockers.
  2. Categorical variables are presented as percentages with absolute numbers between parenthesis. Continuous variables are presented as mean (standard deviation).
  3. AF = amaurosis fugax; BMI = Body mass index; TIA = transient ischemic attack; Time to surgery = time between symptoms (if present) and operation. * = Pearson’s Chi-square; † = Mann-Whitney U test
