^{a} Median difference between FP 24hR and WFR, in grams with 25^{th}, 75^{th} percentiles for the difference of each food category, and median of percentage percentage of the difference in parenthesis (calculated as: % of the difference = ((amount from FP 24hR amount from WFR) / mean amount from WFR)*100).

^{b} Bland Altman analysis, show the antilog values of the mean difference between FP 24hR and WFR, represented as the geometric mean ratio of amounts estimated by the FP 24hR and weighed by WFR, and the 95% limits of agreement, represent the range of proportional agreement between both methods.
