Agreement between each nutrition classification scheme (converted to binary output) measured by the Cohen κ coefficient (with 95% CIs), and frequency of products classified into each binary category¹

¹High degree of alignment highlighted at >50% of sample; high degree of misalignment highlighted at >25% of sample. κ coefficient interpretation using Landis and Koch (36): <0.0 = poor; 0.00–0.20 = slight; 0.21–0.40 = fair; 0.41–0.60 = moderate; 0.61–0.80 = substantial; 0.81–1.00 = almost perfect.
