Compared to the lowest quartile, elevated levels of AIP significantly multiplied the odds of CAD by approximately 1.9–3.8 times (2nd quartile aOR = 1.92, 95% CI: 1.32–2.79, 3rd quartile aOR = 3.05, 95% CI: 2.10–4.42, 4th quartile aOR = 3.80, 95% CI; 2.62–5.53; P-for-trend < 0.001). This evidence concerns the gene AIP and coronary artery disorder.
