Spearman’s correlation analysis in the T2D-DED group revealed a significant correlation between IgA and CRP values (p=0.032; r=0.33) (Figure 2A), but no significant correlation was found between CRP and neutrophil values (p=0.431; r= - 0.03) (Figure 2B). This evidence concerns the gene CD79A and type 2 diabetes mellitus.
