Course of Hyperkalemia in Patients on Hemodialysis

Figure 1

Predialysis sK⁺ concentration at each study visit in placebo patients overall and by predialysis sK⁺ concentration at randomization. Predialysis sK⁺ measurement at randomization (visit 4, day 1) was used for subgroup stratification. No imputation of missing data was conducted. The dashed line represents the upper limit of normokalemia (i.e., sK⁺ 5.0 mmol/L). L represents the LIDI visits. LIDI, long interdialytic interval; SD, standard deviation; sK⁺, serum potassium.
