  1. Abbreviations: BMI, body mass index; AVF, arteriovenous fistula; AVG, Arteriovenous grafts; ICED, Index of Coexistent Disease.
  2. a All P values are two-sided.
  3. If the patient produces ≥200 ml/day of urine, is urea clearance measured from interdialytic urine collection >1.5 ml/min (per 35 L of total urea volume). (0 = no, either produces <200 ml/day or urea clearance ≤ 1.5 ml/min, 1 = yes, 9 = unknown, to be determined during Baseline).
  4. ‡ Continuous and skewed variables are summarized in the form of Median [1st Quartile, 3rd Quartile].
