Upper panel metabolizable energy intake (MEI) from foods versus total energy expenditure by doubly-labeled water (TEEDLW) observed over the 10 days study balance period. The correlation between the two (R2, 0.88) was significant at p = 0.005. Lower panel Bland–Altman plot of between method MEI-DLW differences versus mean of the two methods (R2, 0.39, p = 0.19). ±2SD from the method mean (solid horizontal line) are shown as dashed lines in the figure
