To be clear, I primarily cite natural experiment which I’d argue are not evidentially equivalent to observational studies.
Aside: I only skimmed Croke (2019), but are the null effects surprising given that control children are already given a big boost? -- Plausibly including other GiveWell top charity interventions such as vitamin-A supplementation and vaccines?
The intervention was delivered via a Child Health Day (CHD). Child Health Days are public events, held biannually, in which all parents in a given catchment area are requested to bring pre-school age children to a treatment site to receive a set of basic health services such as Vitamin A supplementation, growth monitoring, and vaccines. At the five Child Health Days held over the course of the project, children in the control parishes who attended the event were offered the standard CHD interventions, while those in the treatment group were also given deworming treatment (400 mg albendazole).
Ah yes, my apologies, I meant natural experiments (or in the case of Croke 2019, a natural experiment caused by an actual experiment).
I suppose it is possible deworming would have a much smaller effect when children also receive these other interventions. However, I would’ve thought many children currently being treated for worms are also receiving such interventions, therefore making it decision-relevant for GiveWell-funded deworming programs?
