>There are people that drink what the study says to drink, every day? Not sure, honestly. They seem to pull this data from a WHO database on health statistics [0]. In stricter terms, you are asking if their estimate of what people drink reflects what they really drink in real life. That is, is the estimate biased? I would expect it to be biased in this case. I am not sure how much it really matters unless you are in charge of large sums of money for public health policy. The best evidence we have suggests alcohol does increase the risk of cancer. Faulty population level alcohol consumption data is not being used for that observation, so it won't matter. Although it would impact the quality of this particular paper. "Controlled" doesn't appear in the original paper so not sure what you mean there. 0. https://www.who.int/data/gho/data/themes/global-information-system-on-alcohol-and-health https://www.who.int/data/gho/data/themes/global-information-...
