In multivariate analysis, only insulin levels (odds ratio = 1.05 [95% confidence interval = 1.01, 1.08], p=0.010), pulmonary disease (5.07 [1.35, 19.050], p=0.016), and family history of CAD (0.38 [0.14, 1.00], p=0.050) were independent predictors of BAC. This evidence concerns the gene INS and lung disorder.
