FFQ, food frequency questionnaire; 24 hR, 24-h recall; CVD, cardiovascular disease; wk, week; SSB, sugar-sweetened beverage.
a
Nuts, seeds, & legumes were not individually analysed since differences in intakes for the majority of individuals were ≤0.
b
Bold P values represent that the κ value is significantly different from 0. This does not imply statistically significant agreement.
