INS and coronary artery disorder: pylori IgG seropositivity is significantly associated with an increased risk of CHD (OR=1.003, 95% CI:1.0001.006, P = 0.048) and increases in peak insulin response (β = 0.214, 95% CI: 0.025–0.403, P = 0.026) or decreases in total free cholesterol levels (β = -0.031, 95% CI: -0.061 to -0.000, P = 0.045), waist circumference (β = -0.073, 95% CI: -0.138 to -0.008, P = 0.027) and waist-to-hip ratio (β = -0.069, 95% CI: -0.136 to -0.002, P = 0.044).
