Forest plot of estimates of association between bacterial vaginosis and cervical human papillomavirus infection. Studies are identified by references. Each study is represented by a black square and a horizontal line, which corresponds to the estimate (ES) and 95% confidence interval (CI) of odds ratios. Area of black squares reflects weight of study in the meta-analysis.
