aItems where calorie information was not available were excluded from the study

b Changes were requested across products that were trayed (e.g. pies), countable in pieces (e.g. scampi), wet/served with a ladle (e.g. curry, rice) or were sliced or portioned by the sites (e.g. cakes). Within these products, sites then agreed to make specific changes to menu items c Proportion of items during the whole intervention period (not including the baseline period) d Sites changed additional items to those requested eNo items within this category were on sale at these sites
