Reliability and validity of assessing energy and nutrient intake with the Vienna food record: a cross-over randomised study

CONSORT flow diagram21 showing the progress of participants through the phases of the crossover randomised study. Blue boxes refer to assessments with the Vienna Food Record (VFR), and orange boxes refer to assessments with the weighed food record (WFR). Participants were classified as under-reporters, if self-reported average daily energy intake was smaller than their basal metabolic rate multiplied by 1.1, where basal metabolic rate was estimated with the Henry equations [13
