If the analysis is repeated with variables: smoking, hypertension, hypercholesterolaemia, diabetes, HDL cholesterol and the IL13 R130Q SNP, the results indicate that, smoking, HDL cholesterol and the IL13 R130Q SNP are still significant risk factors for MI, whereas hypertension, hypercholesterolaemia and diabetes are not, as indicated previously in t-tests and correlation analysis. Here, IL13 is linked to hypertensive disorder.
