Clinical Significance of Serum Galactose-Deficient IgA1 Level in Children with IgA Nephropathy

Figure 3

Serum Gd-IgA1 levels and serum total IgA levels classified by age. (a) Serum Gd-IgA1 levels classified by age. (b) The receiver operating characteristic curve analysis of serum Gd-IgA1 levels for differentiating IgA nephropathy from other glomerular diseases. (c) The receiver operating characteristic curve analysis of serum Gd-IgA1 levels for differentiating IgA nephropathy from healthy controls. (d) Serum IgA levels classified by age. (e) The receiver operating characteristic curve analysis of serum IgA levels for differentiating IgA nephropathy from other chronic kidney diseases. (f) The receiver operating characteristic curve analysis of serum IgA levels for differentiating IgA nephropathy from healthy controls. Bars represent median values. Statistically significant differences between each patient group are shown as , , and . IgAN: IgA nephropathy; MC: minimal change; FSGS: focal segmental glomerulosclerosis; MN: membranous nephropathy; LN: lupus nephritis; HCs: healthy controls; CKD: chronic kidney diseases.
