Figure 3. Meta-analysis of responder rate (RR).
Forest plot showing the pooled effect sizes for responder rate (RR) among patients treated with deep brain stimulation (DBS). The pooled effect size was 0.54 (95% CI, 0.35–0.74), indicating a significant treatment effect. Significant heterogeneity was detected (I² = 95.87%, p < 0.001), and the restricted maximum likelihood model was used for the analysis.
