Fig. 2

Effect sizes represent the optimal frailty index thresholds identified through ROC analysis in each country. Boxes represent the point estimates with their 95% confidence intervals; the size of the box reflects the study weight. The diamond indicates the pooled effect size with corresponding 95% CI, calculated using a random-effects REML model. Heterogeneity statistics include τ² (between-study variance), I² (percentage of variation due to heterogeneity), and H² (relative excess in Q over degrees of freedom).
