Regarding tear cytokine levels from both eyes, analysis revealed a significant main effect of type 2 diabetes diagnosis on IL-6 (F(1,162) = 7.37, P = 0.007; Figure 1E), CXCL8 (F(1,162) = 11.32, P = 0.001; Figure 1F), IL-15 (F(1,162) = 5.14, P = 0.025; Figure 1G), CCL5 (F(1,162) = 14.73, P < 0.001; Figure 1H), and VEGF (F(1,162) = 8.11, P = 0.005; Figure 1I). This evidence concerns the gene IL6 and type 2 diabetes mellitus.
