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

Moderate nitrogen (N) reduction can lower production costs in upland rice but may constrain photosynthesis, N assimilation, and yield formation. Melatonin has the potential to regulate photosynthesis and nutrient metabolism; however, whether it improves the effectiveness of reduced N application by altering functional leaf N allocation remains unclear. A 2-year field experiment was conducted in 2024 and 2025 with four N application rates (0, 120, 160, and 200 kg N ha
