Area under the curves (AUCs) of receiving operator characteristics for the absolute counts of CD19 + CD25 + Bregs and Tregs, serum TGF-ß1, and serum IL-10 as possible identifiers of eGFR ≥ 30 ml/min. The optimal cutoff values were obtained through analysis of coordinate points of ROC curve. The AUC of CD19 + CD25 + Bregs as well as serum TGFβ1 showed statistical significance (AUC = 0.66, p = 0.018, AUC = 0.68, p = 0.006, respectively). AUC values of Treg absolute count as well as serum IL-10 were not significantly increased (AUC = 0.52, p = 0.7; AUC = 0.54, p = 0.5, respectively)
