What have we learned from CONTRAST?

Abstract

The CONvective TRAnsport STudy (CONTRAST) is a large randomized controlled trial which compared on-line postdilution hemodiafiltration and low-flux hemodialysis in terms of mortality and cardiovascular events. This review summarizes and discusses currently available knowledge acquired by CONTRAST, including the main outcome, comparisons of hemodiafiltration to hemodialysis as well as studies performed in subgroups of CONTRAST.
