Reduction ratios of the studied variables at the end of ol-HDF (n = 41), HFR-S (n = 50) and HFR (n = 50) dialysis sessions. For AOPP and TAS the numbers of studied sessions are 30, 28 and 32 for ol-HDF, HFR-S and HFR, respectively. Each dialysis session at each time of the study was included in the analysis. Data are expressed as means ± SE (error bar). * = p < 0.01 vs ol-HDF; # = p < 0.05 vs ol-HDF; ° = p < 0.01 vs HFR-S; ANOVA (RBP, Vitamin A, Vitamin E) or ANCOVA (Vitamin C, TAS, AOPP)
