Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Total energy (kcal) purchased from intervention categories per day after controlling for the total transactions. Total energy purchased is calculated from the total number of sales for all items within the intervention categories 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 (i.e., until the end of week 12). Transactions are defined as the number of unique payments to purchase products in the cafeteria, whereas sales are defined as the total number of individual products that are sold in the cafeteria. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Total energy (kcal) purchased per day from i. non-intervention food and drink categories, and ii. all food and drink products. Total energy purchased is calculated from the total number of sales and the total number of calories for 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 (i.e., until the end of week 12) 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 (i.e., until the end of week 12) | — |
