Forest plot of effect sizes. This forest plot illustrates the effect sizes (e.g., odds ratios, mean differences) from each study included in the systematic review. Each square marker represents the effect size estimate for a specific study, with the corresponding horizontal line showing the 95% CI. The pooled overall effect size, depicted as a diamond, summarizes the magnitude of the relationship between eCPR and neurological outcomes. The plot highlights variability in effect sizes across studies, indicating the need for further research to better understand the impact of eCPR on patient recovery
