Results: “For school attendance, re-analysis showed benefits similar to those originally found in intervention schools for both children who did and did not receive deworming drugs. However, after correction of coding errors, there was little evidence of an indirect effect on school attendance amongst children in schools close to intervention schools. Combining these effects gave a total increase in attendance of 3.9% amongst treated children, which was no longer statistically significant.” We address this claim extensively in Section A.2 above. The results after correction of variable construction make clear that it is impossible to precisely estimate overall deworming externalities on school participation out to a distance of 6 km, as this results in very wide and largely uninformative
