Environmental footprint of a soybean-supplemented low-fat vegan diet in postmenopausal women: a secondary analysis of a randomised clinical trial.
Article in BMJ nutrition, prevention & health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04587154 (Womens Study to Alleviate Vasomotor Symptoms), 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: Dietary patterns that limit or avoid animal products contribute fewer greenhouse gases and require less energy than diets containing more animal products. However, quantifications of these outcomes on a vegan diet in real-life conditions still need to be explored. Methods: In a randomised controlled trial, a low-fat vegan diet supplemented with soybeans led to a significant reduction in hot flashes in postmenopausal women. In this secondary analysis of that study, we hypothesised that the intervention diet would have a reduced environmental impact, greenhouse gas emissions (GHGEs) and cumulative energy demand (CED). 3-day diet records were analysed at baseline and at the end of the 12-week study, and we linked dietary intakes to environmental footprints. Results: Compared with no change in the omnivorous control group, we found that the vegan group had a decrease in GHGEs (p <0.001) of 35% (-662.7 g CO Conclusion: Adoption of a soybean-supplemented low-fat vegan diet significantly reduced cumulative energy demand and GHGEs, important drivers of climate change. Trial registration number: NCT04587154.
