*
Low-GHGE diets are defined as those in the lowest quintile of GHGE (kg eCO2/1000 kcal/d). High-GHGE diets are defined as those in the highest quintile of GHGE per 1000 kcal/d.
†
Determined by Mann–Whitney U test.
‡
Survey results were weighted using the weighting coefficients provided by the UPV/EHU.
