Table 2 Biochemical data from patients dialysing against different dialysate calcium concentrations

From: Do higher dialysate calcium concentrations increase vascular stiffness in haemodialysis patients as measured by aortic pulse wave velocity?

  1. Data expressed in mmol/l unless otherwise stated. Calcium (measured calcium), calcium corrected for serum albumin (Calcium corr), alkaline phosphatase IU/L (ALP), parathyroid hormone pmol/l (PTH), total cholesterol (TChol), high density lipoprotein (HDL), low density lipoprotein (LDL), triglycerides (TG). Drug prescription: HMG CoA3reductase (statin), calcium carbonate (Calcium) g/day, sevelamer g/day, lanthanum carbonate (lanthanum) g/day, calcitriol (ug/wk), and cinacalcet mg/day, percentage patients with parathyroidectomy (PTX). Results expressed as percentage (%), mean ± SD, or median (interquartile range). Patients dialysing with dialysate calcium 1.5 mmol/l (n = 17) added to those dialysing using calcium 1.75 mmol/l (n = 4) summated due to low numbers. *p < 0.05 by Chi square analysis or anova with post hoc correction vs high dialysate calcium (≥1.5 mmol/l) and + p < 0.05 vs calcium dialysate 1.35 mmol/l.
