Meta-analysis reveals biases in clinic performance and advocates for standardized evaluation methods in rural healthcare.
Recent literature on rural clinics in Nigeria has highlighted the need for rigorous evaluation methods to assess clinical outcomes accurately. The analysis employs a mixed-effects logistic regression model to aggregate effect sizes from multiple studies. Uncertainty is addressed through robust standard errors. A specific direction of bias was observed in clinic performance metrics across different study designs, with an estimated proportion of 30% favoring the control group's outcomes. The findings suggest a need for standardised protocols to enhance consistency and reliability in clinical evaluations within rural settings. Rural clinics should adopt validated quasi-experimental methodologies to ensure more accurate assessment of their impact on patient care. Treatment effect was estimated with logit(pᵢ)=β₀+β^ Xᵢ, and uncertainty reported using confidence-interval based inference.
