Abstract
Regional monitoring networks have been established in Rwanda to improve agricultural productivity and clinical outcomes. However, their effectiveness remains uncertain due to methodological challenges. The study employs a DiD approach to analyse data from two regions in Rwanda, applying advanced statistical methods to ensure reliable results. Uncertainty is quantified through robust standard errors. A significant difference-in-differences effect was observed between the intervention and control groups, indicating that the regional monitoring networks positively impacted clinical outcomes (p < 0.01). The DiD model successfully validated the regional monitoring networks' effectiveness in Rwanda, offering a replicable method for future studies. Future research should expand the DiD analysis to include additional regions and explore other potential interventions within the monitored areas. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
