Similarly, CAD patients with the highest quartile of apoB/apoA-I ratio had the multivariable-adjusted HRs of 2.00 (95% CI 1.21–3.31) for all-cause mortality (P for trend = 0.058) and 2.33 (95% CI 1.32–4.14) for CVD mortality (P for trend = 0.023) compared with CAD patients with the lowest of quartile of apoB/apoA-I ratio. The gene discussed is APOA1; the disease is coronary artery disorder.
