Each column’s age category is assigned a letter accordingly:
a
= 19–30y,
b
= 31–50y,
c
= 51–70y,
d
= 71–75y.
Lower case superscript letters in each column indicate statistically significant age group comparisons of mean nutrient intakes after adjusting for total energy intake (p < 0.05), with the letters shown beneath the highest value of the comparisons.
