The two groups had no significant differences in sex distribution; percentage of patients who were on blood pressure-lowering or antihyperlipidemic prescriptions; body mass index (BMI); prevalence of hypertension; diastolic blood pressure (DBP); peritoneal Kt/V; whole clearance of creatinine per week; weekly peritoneal creatinine clearance; weekly creatinine clearance from residual urine; and blood levels of hemoglobin, total cholesterol, albumin, blood urea nitrogen, creatinine, total calcium ion, inorganic phosphorus, and intact parathyroid hormone (iPTH).
