Bland-Altman plot showing the difference in energy-adjusted CO2e assessed by Meal-Q and the WFR plotted against the mean of the two methods, for participants included in the validation analysis (n = 166). Each data point represents one subject. The grey background show the 95% limits of agreement. The Bland-Altman plot for crude CO2e was similar (see Additional file 1: Fig. S2).
