Meta-analysis of the impact of TCM formulations on ABI in gangrene treatment. A Forest plot of the impact of TCM formulations ABI: This plot shows in results and weights in each study, with a pooled mean difference (MD (ot 0.17 and a 95% confidence interval (CI) of [0.11, 0.24], indicating high heterogeneity (I2 = 90%)), which suggests significant variation between of study results. B Sensitivity analysis plot of TCM formulations on ABI in the treatment of gangrene: This plot evaluates the impact of each individual study on the overall effect size by sequentially excluding studies. C Funnel plot assessing the impact of TCM formulations on ABI in gangrene treatment. The symmetrical distribution of data points suggests a low risk of publication bias
