Data represent median differences obtained from 10,000 bootstrapped median values of each NOVA category. High sugar products are defined as food with ≥22.5 g/100 g or drinks with ≥11.25 g/100 g of total sugar; high-fat products are defined as food with ≥17.5 g/100 g of fat or ≥ 5.0 g/100 g saturated fat or drinks ≥8.75 g/100 g of fat or ≥2.5 g/100 g of saturated fat; high salt is defined as food with ≥1.5 g/100 g of salt or drinks ≥0.75 g/100 g of salt. * Values in bold show statistical difference within food groups across NOVA categories (interpreted as significant at a p-value of 0.05). ° Statistical difference (p-value <0.05) within food groups between low and high, total fats, salt and/or total sugar content items. CI: Confidence Interval.
