Figure 2

Urinary IgA was increased in IgAN patients and the renal-disease control patients compared to that in healthy controls, but urinary Gd-IgA1 excretion was higher in patients with IgAN than in renal-disease controls. (a) Urinary IgA was elevated in patients with IgAN as well as in disease controls. (b) Urinary Gd-IgA1 excretion was greater in patients with IgAN than in renal-disease controls ().
(a) Urinary IgA/UCr
(b) Urinary Gd-IgA1/UCr
