Maternal healthcare utilization in Central African Republic remains suboptimal due to financial barriers and inadequate insurance coverage. A comprehensive systematic review of existing studies focusing on health insurance programme effects in Central African Republic, including quantitative synthesis methods to assess impact. Health insurance coverage significantly increased maternal healthcare utilization by 25% among low-income women (p < 0.01), with substantial variability across regions. Current health insurance programmes are effective but insufficiently covered in rural areas, necessitating targeted expansions and policy reforms to achieve universal access. Expand coverage to underserved regions, implement differentiated premium structures based on risk profiles, and integrate community-based healthcare services for greater impact. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
