a Mean difference between FP 24-hR and WFR, expressed in the corresponding units for each nutrient and percentage in parenthesis. The percentage was calculated as: % of the mean difference = ((mean nutrient from FP 24hR- mean nutrient from WFR) / mean nutrient from FWR)*100.
b 95% limits of agreement for the difference between the FP 24-hR and WFR, in the corresponding units for each nutrient and percentage in parenthesis, show the range of under and over-estimation for the agreement between both methods.
