Figure 1 demonstrated that VEGF levels were correlated positively with FBG level (r = 0.483, P < .001), HbA1c level (r = 0.531, P < .001), Th1 percentage (r = 0.366, P = .001), and Th1/Th2 ratio (r = 0.373, P = .001) in the T2DM patients and controls. The gene discussed is VEGFA; the disease is type 2 diabetes mellitus.
