Fig. 4From: Low serum vitamin D concentration is correlated with anemia, microinflammation, and oxidative stress in patients with peritoneal dialysisLow serum concentrations of 25(OH)D are correlated with oxidative stress in patients with PD. Concentrations of MDA (A), SOD (B), and GSH-Px (C) were compared between PD and healthy controls. Violin plot was used to show the data. Spearman correlation analysis of serum concentrations of 25(OH)D with MDA (D), SOD (E), and GSH-Px (F). ***p < 0.001, Mann–Whitney testBack to article page
