*Subset of the n=95 transactions that contained tobacco.
†Estimates exclude one outlier who purchased 19 non-tobacco items (of smoking paraphernalia) with a purchase of two packets of tobacco. Including the outlier in the analysis results in a mean expenditure on non-tobacco items of $6.02 (95% CI: $3.77 to $8.26).
‡Outlet level data are shown to zero decimal places due to low numbers; data in final two columns may not sum to data in ‘Transactions containing tobacco’ column due to rounding to zero decimal points.
§Store sold tobacco below recommended retail price.
¶Store stocked extensive range of takeaway food (eg, including but not limited to hot pies, sandwiches, ice creams and milkshakes, deep fried foods, nachos, chips, sausages, hot chicken, salads, etc). All other stores had a limited range of takeaway food (which in New Zealand typically includes hot pies, sandwiches, ice creams and milkshakes).
**Store had a ‘special offer’ (eg, $1 ice creams, $1.50 pies) or another feature/unique product that could have affected footfall (eg, hot coffee, lottery tickets, postal services).
Dep, socioeconomic deprivation.
