Efficacy of stapes surgery in the osteogenesis imperfecta population in the short term. Studies included for meta-analysis are shown in the table together with the overall result with its corresponding sample size, effect size represented as a proportion (proportion of ears with a postoperative Air Bone Gap (ABG) ≤ 10 dB), 95% confidence interval (CI), and weight for random effect model. The forest plot graphically represents the results. There, each study is represented with a box. The size of each box represents the weight of each study whereas the lines determine their 95% CI. The overall result is shown by a diamond in which the middle indicates the estimate, and the sides represent its 95% CI. Our meta-analysis shows an overall result of 59.01% (95% CI 45.87 to 71.66). The test for heterogeneity table shows Cochrane’s Q test, degrees of freedom (DF), significance level, inconsistency value (\({I}^{2}\)), and its corresponding 95% CI. Significative heterogeneity was found in our results (P < 0.0001) and \({I}^{2}\) of 83.19% (95% CI 72.01 to 89.9). The funnel plot was used to detect publication bias of meta-analysis by plotting the standard error over the proportion (effect size). The diagonal lines represent the 95% CI around the summary effect size. Studies are represented with dots. Publication bias were also assessed with Egger’s and Begg’s test, represented with an intercept, a 95% CI and a significance level; and Kendall’s Tau and significance level, respectively. Results indicate low to no risk of bias across studies (Egger’s test, P = 0.42; and Begg’s test, P = 0.53).
