Fig 1: Typical Gd-IgA1 staining in glomeruli in the CD-IgAN and NOS-IgAN groups. The upper row shows the staining findings of CD-IgAN (A, B, C, and D), and the lower row shows the staining findings of NOS-IgAN (E, F, G, and H). From left to right, glomeruli with negative, + 1, + 2, and + 3 staining intensities are shown (× 400; bar = 50 µm). There was no difference in the deposition site and morphology of Gd-IgA1 due to the presence or absence of CD
