Also, when doing a study, please write down afterwards whether you used intention to treat or not.
Example: I encountered a study that says post meal glucose levels depend on order in which different parts of the meal were consumed. But the study doesn’t say whether every participant consumed the entire meal, and if not, how that was handled when processing the data. Without knowing if everyone consumed everything, I don’t know if the differences in blood glucose were caused by the change in order, or by some participants not consuming some of the more glucose-spiking meal components.
In that case, intention to treat (if used) makes the result of the study less interesting since it provides another effect that might “explain away” the headline effect.
