  • Results presented for patients with measurements at all three time points (baseline, follow-up months 3–5, and follow-up months 10–12). Number of treatments per week and average interdialytic periods are based on the retrospective kinetic modeling data form.

  • a Sessions with reported interdialytic periods >3 days excluded.

  • b Sessions with <3 treatments in week preceding pre/post dialysis blood sampling excluded.
