Change in serum potassium to dialysate potassium gradient categories from baseline to EOT with SZC and placebo. Missing data are not shown. Dialysate potassium gradient data at EOT are missing for the following baseline categories: baseline gradient 2–< 3 mmol/L: SZC n = 2 (16.7%), placebo n = 2 (12.5%); baseline gradient 3–< 4 mmol/L: SZC n = 7 (15.6%), placebo n = 3 (6.0%); baseline gradient ≥4 mmol/L: SZC n = 5 (13.2%), placebo n = 5 (15.6%). EOT, end of treatment; SZC, sodium zirconium cyclosilicate
