aMost nutrient intakes assessed with the WFR were higher than intakes assessed with Meal-Q and MiniMeal-Q (P<.001-.03). Exceptions were beta-carotene intake, which was assessed higher with Meal-Q (P=.03), but was similar comparing the WFR and MiniMeal-Q (P=.19). Thiamine, folate, magnesium, and fiber intake were similar between the WFR and Meal-Q (P=.16-.92). There was no difference in intakes between Meal-Q and MiniMeal-Q (P<.001). (Wilcoxon signed rank test).
bn=162 because of exclusion of 1 participant with implausibly high intake.
cn=160 because of exclusion of 3 participants with implausibly high intakes.
