Nudging Toward Sustainable and Healthy Diets: A Randomized Trial of Young Adults.
Article in Current developments in nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06119165 (Impact of Environmental Nudges on Dietary Quality), which is not on this map. Not yet cited in PubMed.
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.

Abstract
Background: Young adulthood is an optimal time for intervening in dietary behaviors. Young adults in the United States strongly value environmental sustainability, so appealing to these values could be a promising strategy to improve dietary quality. Objectives: We examined whether a "stealth" intervention that explicitly appealed to sustainability (climate-impact labels, climate-focused social comparison messages) while also promoting healthier options (through healthy and sustainable swap recommendations) improved the healthfulness of food selections. Methods: Participants (United States young adults aged 18-25 y) were randomized in Qualtrics to the experimental ( Results: Experimental arm participants selected foods that were 3.9 points healthier than participants in the control arm ( Conclusions: "Stealth" nudges appealing to sustainability while also incorporating health considerations could encourage a wide range of young adults to select more healthful and sustainable foods.This trial was registered at clinicaltrials.gov as NCT06119165 and at aspredicted.org as 147,997.
