INS and coronary artery disorder: pylori IgG seropositivity was 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), decrease in total free cholesterol levels (β = ‒0.031, 95% CI: ‒0.061 to ‒0.000, P = 0.045), decreased 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).
