  1. aPercentage change was calculated by dividing the difference in mean HSRs between 2013 and 2017 by the mean HSR in 2013, multiplied by 100. *Results of Mann-Whitney U tests; p-values < 0.05 were considered statistically significant (shown in boldface). bIn 2013, Kraft Foods and Heinz were two separate companies prior to merging in 2015 and forming The Kraft Heinz Company. However, to enable examination of changes in the nutritional quality of the company’s products over time – and because Kraft Heinz was assessed as one company using the FCR scoring tool – Kraft and Heinz were treated as a single company in 2013, as was done in similar research conducted on the Australian market [24]. **Results of Pearson chi-squared tests; an asterisk indicates that the Fisher’s exact test was used instead due to small group sizes; p-values < 0.05 were considered statistically significant (shown in boldface)
