Table 4 CO2e assessed by first and second Meal-Q for participants in the reproducibility analysis

From: Diet-related greenhouse gas emissions assessed by a food frequency questionnaire and validated using 7-day weighed food records

  Crude kg CO2e per day Energy-adjusted kg CO2e per day
  Mean Median (IQR) Mean Median (IQR)
First Meal-Q 3.86 3.55 (2.20) 3.86 3.58 (1.87)
Second Meal-Q 3.87 3.64 (2.06) 3.87 3.37 (1.94)
Differencea 0.01 0.01   0.01 0.04  
  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
