The polymorphism of VEGFR2 rs2305948 (C > T) exhibited significant correlations with higher risk of CHD (TT/CT vs CC., OR = 1.49, 95% CI: 1.18–1.89, P < 0.001; T vs C, OR = 1.76, 95% CI: 1.52–2.03, P < 0.001, respectively) (Table 3). The gene discussed is KDR; the disease is coronary artery disorder.
