The HRs for coexisting T2D‐CHD in the multivariate‐adjusted model (Model 2) was 1.69 (95% CI, 1.05–2.89, p for trend 0.05) for cholesterol/HDL‐C, 1.85 (95% CI, 1.04–3.29, p for trend 0.002) for triglyceride/HDL‐C, 1.69 (95% CI, 1.01–2.31, p for trend 0.03) for non‐HDL‐C/HDL‐C, and 1.89 (95% CI, 1.03–2.46, p for trend 0.05) for apoB/apoA1 (Model 2, Table 3). The gene discussed is APOA1; the disease is type 2 diabetes mellitus.
