Note: SD = standard deviation. Additional analysis using general linear models to predict the change in sodium while including establishment as a covariate produced the same results and confirmed that establishment is not a covariate. Data for baked goods, desserts and side dishes are provided in Appendix 1 (Supplementary Table 2, available at www.cmajopen.ca/content/2/4/E343/suppl/DC1). Data for changes in sodium density (sodium per 100 g) in each category are provided in Appendix 1 (Supplementary Table 3, available at www.cmajopen.ca/content/2/4/E343/suppl/DC1).
