  1. Crude and energy-adjusted daily mean, median and IQR of daily CO2e assessed by first and second Meal-Q for participants in the reproducibility analysis (n = 87)
  2. IQR Interquartile range, CO 2 e Carbon dioxide equivalents
  3. aIndividual differences between the first and second Meal-Q. There was no statistically significant difference in CO2e between first and second Meal-Q. Crude P = 0.58, energy-adjusted P = 0.49, for Wilcoxon signed rank test
