Thanks for providing this study. This reminds me of the Iron Law of Evaluation: https://www.gwern.net/docs/sociology/1987-rossi https://www.gwern.net/docs/sociology/1987-rossi The Iron Law refers social program interventions but I think it is applicable to a lot of health interventions too. https://www.gwern.net/docs/sociology/1987-rossi https://www.gwern.net/docs/sociology/1987-rossi
