Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Total energy (kcal) purchased from intervention food categories per day after controlling for the total transactions. This measure is calculated from the total number of sales for all items within an intervention food category and the total number of calories for each of these items. Sales data are recorded using electronic tills every day of operation during the trial. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Total energy (kcal) purchased per day of analysis from (a) non-intervention food categories, and (b) all food and drink products, after controlling for the total sales/transactions. This measure is calculated from the total number of sales for all items within an intervention food category and the total number of calories for each of these items. Sales data are recorded using electronic tills every day of operation during the trial. 2. Total revenue from each cafeteria. This is calculated from the number of all items sold in the cafeterias and the price of each of these items. These data will be collected using the electronic tills for every day of operation for all cafeterias during the length of the trial. 3. Overall sales data from any vending machines located in each distribution centre. This consists of the total number of individual product sales from vending machines across each distribution centre (i.e. the wider building that houses the cafeterias in which we are intervening). These data will be collected every day of operation for all distribution centres during the length of the trial. | — |
