CMV: cytomegalovirus, C. pneumoniae: Chlamydophila pneumoniae, DM: diabetes mellitus, H. pylori: Helicobacter pylori, SE: standard error.
Multiple logistic regression analysis was done with coronary artery disease (CAD) as the outcome (dependent variable). The predictor covariates (independent variables) were C. pneumoniae, CMV, H. pylori, DM, hypertension, dyslipidaemia, and obesity. It was found that H. pylori, hypertension, obesity, and dyslipidaemia were significant risk factors for CAD.
