  1. Mean, median and IQR of daily CO2e for participants included in the validation analysis (n = 166)
  2. IQR Interquartile range, CO 2 e Carbon dioxide equivalents, WFR Weighed food record. aMeal-Q /WFR. There was a statistically significant difference in CO2e between WFR and Meal-Q. Crude P = 0.00, Energy-adjusted P = 0.00, for Wilcoxon signed rank test
