Type-1, -2, and -3 CKDs correspond to diabetic kidney disease, nephrosclerosis, and glomerulonephritis, respectively. The upper panel (A) indicates the numbers of all samples and samples from males and females, as well as age (average ± SD). The lower panel (B) summarizes the serum antibody levels examined by AlphaLISA using purified UBE2E3-GST protein as an antigen, as described in the legend of Table 1. P values were calculated using the Kruskal–Wallis test (Mann–Whitney U test with Bonferroni correction applied). P values < 0.05 and positive rates > 10% are marked in bold text. A scatter dot plot of the same results is shown in Figure 2D
