Data-driven nitrogen management benchmarks support China's wheat self-sufficiency by 2030.
Article in Nature food, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Targeted improvement pathways for crop production are needed to meet growing food demand, but quantitative benchmarks are still lacking in China. Here we establish nitrogen (N) management benchmarks for wheat production at regional-to-country scales using a modified approach outlined by the EU Nitrogen Expert Panel, defined as meeting both the requirements for targeted crop N output and the threshold for N surplus. A large-scale survey of farmers shows that only 20% of China's wheat harvested area met N management benchmarks. Optimized N management, soil fertility and climatic factors account for 70% of the effect on N management benchmarks; the combination of these contributors is projected to increase China's wheat harvested area that meets N management benchmarks to 75% by 2030. With this, wheat production would increase by 12%, sufficient to achieve wheat self-sufficiency without imports. We demonstrate how N management benchmarks can be achieved under future climate change scenarios.
