Do nutritional warnings encourage healthier choices on food ordering websites? An exploratory experimental study in Uruguay.
Trial report in Public health nutrition, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 2 of them syntheses 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
objectiveTo evaluate if the inclusion of nutritional warnings in food ordering websites can discourage consumers from purchasing foods with excessive content of nutrients associated with non-communicable diseases (NCD).
designParticipants were randomly assigned to one of the two experimental conditions: control (n 225) or nutritional warnings (n 222). Nutritional warnings corresponded to separate black octagonal signs containing the word 'Excess' followed by the corresponding nutrient: total fat, saturated fat, sugars and sodium. Participants were asked to purchase a lunch for themselves using a simulated food ordering website.
settingOnline study in Uruguay.
participantsConvenience sample of 447 Uruguayan participants, recruited using social media.
resultsIn the control condition, 76 % of the participants selected a dish or a beverage with excessive content of at least one nutrient in the simulated food ordering website. When nutritional warnings were included, this percentage significantly decreased to 62 % (P = 0·002). In addition, nutritional warnings caused a significant reduction in the percentage of participants who selected dishes with excessive content of total fat: 50 % v. 62 % (P = 0·012).
conclusionsResults from the present work provide preliminary evidence that the inclusion of nutritional warnings in food ordering websites could discourage consumers from selecting dishes and beverages with excessive content of nutrients associated with NCD.
