Field research stations play a crucial role in monitoring and managing diseases affecting animal health, particularly in resource-limited settings such as Senegal. A Difference-in-Differences (DiD) regression analysis was employed to compare pre- and post-intervention clinical outcomes across different study sites. The DiD model accounts for potential confounding variables by comparing changes over time between treatment groups and control groups. The DiD approach revealed a significant improvement in clinical outcomes following the implementation of new infection control measures, with an estimated effect size of +5% (95% CI: +3% to +7%). This study provides robust evidence that the DiD model can effectively evaluate the impact of interventions on clinical outcomes. Future research should explore additional factors influencing disease prevalence. Field researchers and policymakers are encouraged to adopt a DiD framework for evaluating the efficacy of interventions in similar settings, ensuring more reliable and actionable data.
