Hypothesis

Does deworming improve growth and school performance in children?

Conclusion

Mass school-based deworming is highly cost-effective and significantly improves school participation and health outcomes.

Supporting Evidence

  • Deworming is shown to be a cost-effective way to increase school participation.
  • Studies indicate that deworming has a high benefit to cost ratio.
  • Treatment externalities can lead to underestimation of the true effects of deworming.

Takeaway

Deworming helps kids grow better and do better in school, and it doesn't cost much to do.

Potential Biases

Potential bias due to reliance on reported data for school attendance and sample attrition affecting results.

Limitations

Many studies on deworming do not adequately address treatment externalities, cognitive outcomes, and sample attrition.
