Figure 2

Forest plot of hazard ratio or treatment effect size. Hazard ratios of recurrent stroke for patent foramen ovale (PFO) closure by each randomized clinical trial is listed. Mean represented by gray box (size is proportional to the weight) and black lines on either end represents 95% confidence intervals. Summary measure (dotted line through gray diamond) and associated confidence interval (lateral tips of diamond) assumes random effects model. Right of the solid vertical line is no benefit from treatment, left represents benefit. HR indicates hazard ratio, CI is confidence interval.
