The correlation between CCR2 and Lee’s grade in IgAN children. Fifteen patients were divided into 2 groups, low grade group (Lee’s grade I to II) (n = 7, A: middle), and high grade group (grade III to IV) (n = 8, A: right). The Bar of A was 50 µm. Image J analysis software was used to calculate the relative optical density (OD) of CCR2 DAB staining in control group, low and high grade group (B). The correlation analysis between the relative OD value of CCR2 and Lee’s grade was performed by Spearman’s correlation tests (C). Compared with control group, *P < 0.05, **P < 0.01; Comparison between Lee’s grade groups,.^{# #}P < 0.01
