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

Background: Food-based dietary guidelines (FBDG) aim to support health and reduce the environmental impacts, including the dietary carbon footprint (CF). Children's dietary CF is largely unknown. Objectives: The aim of this study was to estimate the CF of children's diets, identify the main food groups contributing to CF across different age groups, and to assess how adherence to FBDG might influence CF. Methods: The study included participants in 5 age groups (3, 5, 6, 9, and 15 y; Results: Mean total dietary CF (kg CO Conclusions: Meat and dairy were the largest contributors to dietary CF, with discretionary foods ranking third among children aged ≥6 y upward. The results highlight the potential positive climate impact of transitioning toward more plant-based diets and adhering to the FBDG.
