Although CHD patients displayed an increased proportion of diabetes mellitus (25.0% vs. 12.9%, p = 0.042), elevated C‐reactive protein (CRP) level (9.1 (6.7–11.8) mg/L vs. 5.5 (2.4–10.2) mg/L, p < 0.001), and higher Gensini score (39.3 ± 25.0 vs. 1.3 ± 2.0, p < 0.001) compared to controls, majority of the clinical features were similar between these two groups (all p > 0.05) (Table 1). The gene discussed is CRP; the disease is diabetes mellitus.
