Wen D, et al. - Researchers performed a meta-analysis that included eight cohort studies and six case-control and cross-sectional studies in order to evaluate how hepatitis C virus (HCV) infection is associated with coronary artery diseases (CAD). There was no evidence of publication bias. Two independent reviewers extracted the data and calculated the pooled odds ratio and relative risk with 95% confidence interval using the fixed and the random effects models. Outcomes suggested HCV infection as a risk factor for CAD.
