Community health centres (CHCs) play a crucial role in healthcare delivery in Ethiopia's rural and urban settings. A systematic literature review employing multilevel regression analysis with robust standard errors to evaluate the impact of CHCs on health outcomes in Ethiopia. CHCs showed a significant reduction (p < 0.05) in maternal mortality rates by 18% after implementing evidence-based interventions, indicating effective risk mitigation strategies. Multilevel regression analysis provided nuanced insights into the role of CHCs in improving health outcomes and reducing risks across various geographical and socio-economic contexts in Ethiopia. Further research should explore scalability of these findings to other regions and incorporate longitudinal data for comprehensive impact assessments. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
