When all patients with diabetes were considered, there were significant correlations between vitreous fluid levels of sVEGFR-2 versus SCF (r = 0.950, P < 0.001), sVEGFR-2 versus s-kit (r = 0.941, P < 0.001), and SCF versus s-kit (r = 0.970, P < 0.001) (Table 5). This evidence concerns the gene KITLG and diabetes mellitus.
