Figure 2. Forest plot showing the effect of rhG-CSF on clinical pregnancy rates (CPRs) in women with reproductive failure. The meta-analysis revealed no significant benefit among patients with recurrent pregnancy loss (RPL; OR: 0.25; 95% CI, 0.01-9.33; I²=93%), while a significant improvement was observed in those with recurrent implantation failure (RIF; OR: 1.73; 95% CI, 1.17-2.55; I²=17%). Overall, the combined effect was not statistically significant (OR: 1.16; 95% CI, 0.48-2.80; I²=86%).
