Multiple regression analysis results—association between global food score and FOPL group (adjusted for design factors and covariates as planned).

	MTL vs. Control RR (95%CI)	N-S vs. Control RR (95%CI)	WL vs. Control RR (95%CI)	PC vs. Control RR (95%CI)	N-S vs. MTL RR (95%CI)
Score (−5, +5) Regression (coefficients)	1.7 (1.6, 1.9) p < 0.001	2.1 (1.9, 2.2) p < 0.001	1.4 (1.3, 1.6) p < 0.001	0.1 (−0.02, 0.3) 0.09	0.3 (0.2, 0.5) p < 0.001

Global food score was an aggregated score of correct ranking in the five food products, range −5 to +5 (− indicates worsening and + indicates improvement); all analyses adjusted for stratification factors (year of recruitment to panel, sex, age, government office region, household income) and covariates: ethnicity, highest education level, household composition, food shopping responsibility, current FOPL use. MTL: Multiple Traffic Lights; N-S: Nutri-Score; WL: Warning label; PC: Positive Choice tick; RR: Relative Risk; CI: Confidence Interval.
