The relative validity of the FFQ\u2010HD was assessed using the mean of two 24\u2010h food recall (24hR) adjusted for within\u2010subject variability as a reference method. We also performed Pearson correlations, and agreement between tertile, kappa statistics, and Bland\u2013Altman scatter plots were validated.
