a
SD = standard deviation
b
% difference estimated mean nutrient intakes from DR-AFFQ/DR. Percent differences are not statistically different between methods for any nutrient, p≤0.05.
c
Pearson’s correlations between DR and AFFQ estimated mean nutrient intakes are log transformed and energy-adjusted (standardized residual method) p ≤ 0.05.
d
Pearson’s correlation between DR and AFFQ for Energy. Energy is Log transformed p ≤ 0.05.
e
Dietary calcium plus calcium supplement (mg).
