Ah ha, I see.
The study did not compare vegetarian to vegan, as I imagine there are too few vegan SDAs to make a study.
Well, from the abstract:
Diet was assessed at baseline by a quantitative food frequency questionnaire and categorized into 5 dietary patterns: nonvegetarian, semi-vegetarian, pesco-vegetarian, lacto-ovo–vegetarian, and vegan.
In more detail:
Dietary patterns were determined according to the reported intake of foods of animal origin. Thus,
vegans consumed eggs/dairy, fish, and all other meats less than 1 time/mo;
lacto-ovo–vegetarians consumed eggs/dairy 1 time/mo or more but fish and all other meats less than 1 time/mo;
pesco-vegetarians consumed fish 1 time/mo or more but all other meats less than 1 time/mo;
semi-vegetarians consumed nonfish meats 1 time/mo or more and all meats combined (fish included) 1 time/mo or more but no more than 1 time/wk;
and last, nonvegetarians consumed nonfish meats 1 time/mo or more and all meats combined (fish included) more than 1 time/wk.
For some analyses, the 4 vegetarian categories (vegan, lacto-ovo–vegetarian, pesco-vegetarian, and semi-vegetarian) were combined as “vegetarian.”
