After adjustment for age, use of statins, use of aspirin and history of coronary heart disease, the adjusted ORs for IL-17A, IL-17F, IL-21, IL-22, IFN-γ, IL-10, IL-9, and IL-6 were 2.58 (95% CI, 1.47–4.55; P = 0.001), 1.82 (95% CI, 1.05–3.16; P = 0.034), 2.08 (95% CI, 1.17–3.72; P = 0.013), 2.18 (95% CI, 1.26–3.79; P = 0.006), 2.47 (95% CI, 1.36–4.49; P = 0.003), 2.21 (95% CI, 1.25–3.94; P = 0.007), 2.74 (95% CI, 1.49–5.05; P = 0.001) and 2.50 (95% CI, 1.40–4.47; P = 0.002), respectively (highest vs lowest tertile) (Table 2). This evidence concerns the gene IL9 and coronary artery disorder.
