Table 2 Effects of price, information nudge and combination condition on total meat purchases in gram per household per week in the virtual supermarket using linear regression analyses

From: Less meat in the shopping basket. The effect on meat purchases of higher prices, an information nudge and the combination: a randomised controlled trial

  Price condition (n = 133) Information nudge condition (n = 126) Combination condition (n = 121)
Model 1 − 162 − 347 23 −10 − 198 178 −367 −557 −178
Model 2 −144 −331 43 1 −188 189 −386 −579 −193
  1. Data are regression coefficients (β) with 95% confidence intervals. The adjusted amount of meat purchases per household per week and per person per day based on the conditions’ average household size were, respectively, 1084 and 67 g in the control condition, 940 and 61 g in the ‘price condition’, 1085 and 65 g in the ‘Information nudge condition’ and 698 and 4 g 2 in the ‘Combination condition’
  2. Model 1 = adjusted for household size;
  3. Model 2 = model 1 + adjusted for gender (male, female, other), BMI (continuous), education (low, moderate, high)
  4. β represents average difference in gram per household per week compared with the control condition
