3. Figure 2
Meta-analysis plots. Each study is shown as an odds ratio (OR) estimate (black squares), with whiskers corresponding to 95% confidence intervals (CI). The size of the squares is proportional to the weight the study contributes to the meta-analysis. Studies are ordered by year of publication. Also shown is the summary OR (diamond) by fixed effects calculations. Vertical reference lines show the line of no association (continuous line) and the overall odds ratio (discontinuous line). Values greater than 1 favor treatment with vaginal progesterone gel.
