The correlation between 25(OH)D and Treg or related cytokines. (A) Dot plot of serum concentrations of 25(OH)D in RSM (N = 121) and HD (N = 121). (B) Linear regression was applied to analyze the correlation between 25(OH)D level and Treg. (C) The blue histogram represents the distribution of serum vitamin D. The black solid line represents the fitting curve of serum vitamin D and peripheral blood Treg, and the black curve represents the 95 % confidence interval of the curve. (D–F) Correlations between serum 25(OH)D level and serum IL-17, IL-10 and IFN-γ. Data represent the mean ± SEM. Statistical differences were determined by a two-tailed unpaired Student t-test. ***p < 0.001 as compared with HD.
