Randomised controlled trial in an experimental online supermarket testing the effects of front-of-pack nutrition labelling on food purchasing intentions in a low-income population.
Trial report in BMJ open, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe Nutri-Score, a front-of-pack nutrition label, has been adopted in 2017 in France but its impact on low-income populations is unknown, and they are more at risk of having unhealthy diets. The present study assessed the effects of the Nutri-Score on the nutritional quality of purchasing intentions among low-income individuals, compared with the current French labelling situation: references intakes (RIs) and no label, using a three-arm parallel-group randomised controlled trial.
methodsLow-income active adults from the NutriNet-Santé cohort (household income below €1200/month) were asked to perform a shopping task in an experimental online supermarket after being randomised in one of the three conditions (Nutri-Score, RIs or no labelling). The main outcome was the overall nutritional quality of the virtual shopping cart, assessed with the French-modified Food Standards Agency Nutrient Profiling System (FSAm-NPS), and secondary outcomes were the nutrient content of the shopping carts. 524 subjects were randomised, and 336 included in the analyses.
resultsThe Nutri-Score resulted in the highest overall nutritional quality of the shopping cart, as reflected by a FSAm-NPS score (1.86 (SD 3.59) points) significantly lower (reflecting higher nutritional quality) than the RIs (3.21 (SD 4.14) points, p≤0.05) but not significantly lower than no label (2.60 (SD 3.09) points, p=0.3). The Nutri-Score also resulted into significantly lower contents in calories and saturated fatty acids in the shopping cart, compared with the RIs only (p≤0.05).
conclusionThe implementation of the front of pack nutrition label Nutri-Score, adopted in France and in different European countries, appears to have the potential to encourage purchasing intentions of foods from higher nutritional quality among low-income individuals, compared with the RIs label promoted by food manufacturers.
