Baseline patient characteristics according to dialysate potassium concentration.

Count data are expressed as number (percentage) and continuous values are expressed as mean ± SD if normally distributed or median (interquartile range) if skewed.Abbreviations: KD, potassium dialysate; Ca, calcium; EF, ejection fraction; ESRD, end-stage renal disease.†Patients who had at least one prescription of a 1.0 mEq/L potassium dialysate.‡Patients who had at least one prescription of a 2.5 mEq/L calcium dialysate.§Preserved EF refers to patients with an ejection fraction of 55% or more.Baseline patient characteristics according to dialysate potassium concentration.
