Protein variations during and after hemodialysis. Cystatin C (a) and albumin (b) variations during (clear) and after (dark) hemodialysis. Results are expressed in percentage of value at D0 as mean ± SEM. (c) Ratio of percentage of value at D0 of IL-6, IL-8, and IL-10 versus cystatin C. IL-6 (about 26 kDa), IL-8 (about 8 kDa), cystatin C (about 13 kDa), IL-10 (about 19 kDa), and albumin (about 68.5 kDa). *P < 0.05 versus D0; Friedman test.
