  1. aVascular access used at dialysis initiation
  2. bHD prescription parameters represent the last HD, prescribed thrice-weekly by treating provider prior to study enrollment and randomization
  3. Percentages may not total 100 because of rounding. KDRD denotes kidney dysfunction requiring dialysis, HD hemodialysis, SD standard deviation
