From: Time-averaged serum potassium levels and its fluctuation associate with 5-year survival of peritoneal dialysis patients: two-center based study

Kaplan-Meier survival curves for mortality according to time- averaged serum potassium fluctuation All-cause mortality (A); Cardiovascular mortality (B).

Patients were categorized into four groups according to quartiles (Q) of standard deviation of time-averaged serum potassium: Q1: <0.39 mEq/L; Q2: 0.39 mEq/L to <0.52 mEq/L; Q3: 0.52 mEq/L to <0.69 mEq/L; Q4: ≥0.69 mEq/L. There was no difference of the levels of time-averaged serum potassium among the 4 SD groups (p = 0.49, Table 4).
