MOESM1 of Removal of large middle molecules via haemodialysis with medium cut-off membranes at lower blood flow rates: an observational prospective study

Additional file 1. Pre- and postdialysis serum levels of the various parameters among the different treatment modalities. Data are expressed as means ± SDs or medians (Q1–Q3). The postdialysis levels of the large middle molecules and albumin were corrected for haemoconcentration. The P was given for the overall result of pre- and postdialysis between the three groups and < 0.05 was considered statistically significant. SD: standard deviation; NS, not significant; HD: haemodialysis; OL-HDF: online haemodiafiltration; MCO: membrane cut-off; β2M: β2-microglobulin; FLC: free light chain; FGF: fibroblast growth factor
