Behavioral interventions to motivate plant-based food selection in an online shopping environment.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Encouraging consumption of plant-based food products can help mitigate the impact of dietary choices on climate change. Research suggests that modifying environments in which people make purchasing decisions has the potential to achieve behavioral changes toward sustainable consumption. We examine the impact of two behavioral interventions, carbon footprint labeling, and product categorization, to promote sustainable food selection in an online grocery shopping environment. Online grocery shopping data collected from 2,359 US participants show that carbon footprint labels increased the selection of plant-based food products by 37% and categorization increased it by 25%. A combination of both nudges increased plant-based food selection by 32%. Participants underestimated the environmental impact of different types of foods despite exposure to carbon footprint information. As the global market for online grocery shopping continues to grow, this study presents a potential for simple and scalable interventions in online shopping environments to encourage sustainable choices.
