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

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

	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

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’
Model 1 = adjusted for household size;
Model 2 = model 1 + adjusted for gender (male, female, other), BMI (continuous), education (low, moderate, high)
β represents average difference in gram per household per week compared with the control condition
