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

backgroundThe precise regulation of nitrogen supply after anthesis for maize can be achieved by blending urea and controlled-release urea (CCU) one-off application. However, the dynamic optimization governing source-sink allocation and patterns underlying synergistic carbon-nitrogen regulation remain poorly understood. We investigated the physiological and molecular mechanisms associated with carbon and nitrogen metabolism in maize under various controlled-release urea and conventional urea treatments.

resultsThe experiment included five fertilization treatments: CK (no nitrogen) and four treatments at 180 kg N ha

conclusionsThese findings suggest that CCU may support the preferential distribution of assimilation products to grains through the synergistic regulation of slow nitrogen release and carbon-nitrogen metabolism. This study provides insights into the regulation of maize metabolism and offers guidance for the efficient utilization of nitrogen under one-off application of nitrogen.
