Sulfur Hexafluoride (SF₆) versus Perfluoropropane (C₃F₈) in the Intraoperative Management of Macular Holes: A Systematic Review and Meta-Analysis

Figure 2

Forest plot of the proportion of patients who achieved anatomical closure following the use of SF₆ gas. Meta-analytic pooling of the proportion of patients who achieved anatomical closure following surgery in the SF₆ group. Pooled estimate was 91.73% (95% confidence interval: 88.40% to 94.55%, I²: 38.03%, value for heterogeneity = 0.126). Size of the squares is proportional to the number of cases in the study. Error bars represent 95% confidence intervals. The diamond shape represents the pooled estimate.
