IL-6 adsorption clearance of CHDF using PMMA and AN69ST. Box plot, center lines show the medians; box limits indicate the 25th and 75th percentiles; whiskers extend to minimum and maximum values. White boxes indicate no settings, light-grey boxes indicate QD settings, and dark-grey boxes indicate QF settings. IL-6, interleukin-6; QF, filtration flow rate; QD, dialysate flow rate; CHDF, continuous hemodiafiltration; PMMA, polymethyl methacrylate; AN69ST, polyethyleneimine-coated polyacrylonitrile
