Reports means and 95% confidence intervals. (A) Reports mean dialysate concentrations of inflammatory mediators at T1 (baseline) and T3 (after switching treatments) in the intention to treat population. Comparison of treatments: MCO versus high flux dialysis was done using unpaired ANOVA on n = 42 MCO treated versus 39 high flux treated patients × sample pairs, comparable results were obtained on the per protocol population using linear mixed models (not shown). (B) Mean YKL-40 serum levels were assayed at all 4 study timepoints in the ITT population after the dialysis session (4 h—sample). (C) Mean YKL-40 serum levels were assayed at all 4 study timepoints in the ITT population before the dialysis session (0 h—sample) (B, C) The thin connecting horizontal lines between timepoints (T1–T4) represent repeated measures from subject IDs within sequence 1 (MCO → wash out → high flux). A linear mixed effects model was built with subject ID, nested in sequence, as a random effect and treatment (MCO = 1), period and sequence as the main effects. A P value for treatment < 0.05 in the absence of carry over effect was considered statistically significant.
