  1. Note. Site 2 had 394 temporary agency staff and Site 6 had additional 476 agency staff for which they did not have demographic information and are therefore not included in this Table. The mean values denoted in the sales data reflect averages of actual items sold. aEnergy estimates for drinks at Site 3 are expressed per 100 ml. bSite 5 does not sell low calorie soft drinks (this site produces soft drinks which are freely available to all staff, including sugar-free and sugar-sweetened varieties). cSite 2 offered only a limited selection of snacks sold under the same till button, hence the median energy value was used to estimate energy content of snacks at this site
