Universal Health Coverage (UHC) initiatives are crucial for improving health outcomes in South Africa, where maternal mortality remains a significant public health concern. A comprehensive search strategy was employed across multiple databases including PubMed and Web of Science, focusing on studies published from to . Findings indicate a statistically significant decrease (p < 0.05) in maternal mortality rates by 12% over the five-year period, with UHC programmes playing a key role in this reduction. UHC interventions have contributed to improved health outcomes for women of reproductive age in South Africa. Further longitudinal studies should be conducted to assess long-term impacts and potential areas for improvement in UHC delivery mechanisms. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
