Comparison of survival between dialysis patients with incident high-flux hemodialysis versus on-line hemodiafiltration: A single center experience in Saudi Arabia.

Conventional hemodialysis (HD) is the most common treatment modality used for renal replacement therapy. The concept of HD is based on the diffusion of solutes across a semipermeable membrane. Hemofiltration (HF) is based on convective transport of solutes; hemodiafiltration (HDF) is based on combined convective and diffusive therapies.
