1 · What the graph read from 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.

2 · The registry

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

Sustainable food system transitions will likely require targeted dietary strategies, yet most models typically estimate environmental footprints at the aggregate level and overlook variation between individuals and contexts. Here we develop a globally harmonized model integrating individual food intake and supply chain data to estimate diet-related climate, water and land impacts, and dietary quality using the Alternative Healthy Eating Index (AHEI), across 72 socio-demographic subgroups in 165 countries. We find large disparities across groups. Highly educated urban men aged 15-34 years have the greatest emissions (median, 5.66 kgCO
