Factors associated with microinflammation in CKD. a- Correlation between indoxyl sulfate (IS) and RITNFα, c- correlation between p-cresyl sulfate (PCS) and RITNFα, e- correlation between indole acetic acid (IAA) and RITNFα, g- correlation between urea and RITNFα. b- IS levels in subgroups with hsCRP < or ≥ 5 mg/l. d- PCS levels in subgroups with hsCRP < or ≥ 5 mg/l. f- IAA levels in subgroups with hsCRP < or ≥ 5 mg/l. h- Urea levels in subgroups with hsCRP < or ≥ 5 mg/l. Spearman correlation test for A, C, E, G and Mann-Whitney test for B, D, F, H: n = 51 for hsCRP < 5 mg/l, n = 18 for hsCRP ≥5 mg/l, except for PCS: n = 37 for hsCRP < 5 mg/l, n = 15 for hsCRP ≥5 mg/l
