Table 1 Demographics of 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. Results expressed as percentage (%), mean ± SD, or median (interquartile range). Body mass index (BMI), medical history hypertension, ischaemic heart disease (myocardial infarction, coronary artery stenting or bypass surgery), transient ischaemic attack or cerebrovascular accident (TIA/CVA) or peripheral vascular disease (PVD). Arteriovenous fistula (AVF), dialysis vintage in months (vintage mo), dialysis session time (session). 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 calcium dialysate (≥1.5 mmol/l).
