Yeah, it says something like that in the study. "Participants who consumed a relatively low percentage of total energy from carbohydrates (ie, participants in the lowest quantiles) were more likely to be young, male, a self-reported race other than black, college graduates, have high body-mass index, exercise less during leisure time, have high household income, smoke cigarettes, and have diabetes."
LOL
But it's still misleading of course, because most people won't bother to actually read it.
