HP and coronary artery disorder: In multivariable adjusted Cox regression models, having HbA1c < 6.5% compared with 7.0-7.9% was not significantly associated with a lower risk of CAD among participants with the Hp2-2 phenotype (aHR 0.80, 95% CI 0.57–1.12) but was among those with the non-Hp2-2 phenotype (0.71, 0.55–0.90 p, Hp phenotype*HbA1c interaction = 0.79) (Table 2).
