Ok, so their observed effect ("significantly increased overall symptoms") is almost certainly due to gluten. Those are indeed good probabilities. I'm interested in how large an effect "significantly increased" means. I suspect that this is defined a little more rigorously in the actual text, but it doesn't seem to be in the abstract.

> almost certainly due to gluten Even if you ignore all the messiness of actually existing scientific practice, the math alone doesn't quite say that. It depends on your prior[0] and the power[1] of the study.
