  1. GDA Guideline Daily Amount; MTL Multiple Traffic Light; WL Warning Labels; NPSC Nutrient Profiling Scoring Criterion
  2. Bolds indicate significant differences (p < 0.05) with GDA. No differences were observed between MTL and WL groups. Differences were tested with unadjusted linear regression models
  3. Sample sizes vary across food groups as follows: Non-dairy beverages: GDA = 584, MTL = 586, WL = 565; Breakfast cereals: GDA = 680, MTL = 679, WL = 683; Dairy: GDA = 708, MTL = 710, WL = 711; Ready-made foods: GDA = 585, MTL = 581, WL = 585; Salty snacks: GDA = 623, MTL = 651, WL = 618
  4. a A lower score corresponds to higher nutritional quality
  5. b Marginally significant difference (p < 0.06) with GDA
