Survival of incident patients on high-volume online hemodiafiltration compared to low-volume online hemodiafiltration and high-flux hemodialysis

Background Hemodiafiltration is becoming a preferred treatment modality for dialysis patients in many countries. The volume of substitution fluid delivered has been indicated as an independent mortality risk factor. The aim of this study is to compare patient survival on three different treatment modalities: high-flux hemodialysis, low-volume online HDF (oHDF) and high-volume oHDF.
