Figure 6 Meta-analysis of postoperative complication rates in both groups. Including 6 studies, analyzed using a fixed-effects model. Pooled odds ratio = 0.96 (95% confidence interval: 0.74-1.24, P = 0.76), suggesting no statistically significant difference between groups. Heterogeneity test I2 = 0% (P = 1.00), with excellent homogeneity among studies. Squares represent individual study effect sizes, and the diamond represents the pooled effect size.
