On-line haemodiafiltration versus haemodialysis: stable haematocrit with less erythropoietin and improvement of other relevant blood parameters.

Background: Controlled randomised studies to prove improved cardiovascular stability and improved anaemia management during on-line haemodiafiltration (oHDF) are scarce.

Methods: 70 patients were treated with both haemodialysis (HD) and oHDF in a cross-over design during 2 x 24 weeks at a dialysis dose of eKt/V> or =1.2.
