Forest plot of mean age. This forest plot displays the mean age of patients across the studies included in the systematic review. Each horizontal line represents the 95% confidence interval (CI) for the mean age in each study, whereas the square markers indicate the pooled estimate of the mean age for each study. The plot shows variability in the age distribution across studies, highlighting how age might influence neurological outcomes after eCPR. The overall estimate is provided as a combined measure across studies
