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

Introduction: Blending urea (U) with slow-release N fertilizer (R) can improve the synchrony between N supply and crop demand, while mitigating N losses to the environment. However, cultivar-specific responses to varied U/R blending ratios under rainfed conditions remain poorly characterized. Methods: In this study, two dominant maize cultivars (ZD958 and QL14) widely planted in Northwest China were selected as experimental materials. Five fertilization treatments (U, R, and three U/R blending ratios: UR1, UR2, UR3) each at two N rates (N1: 180 kg·ha Results: The results showed that UR treatments generally achieved higher grain yield and N use efficiency (NUE), while reducing cumulative NH Conclusion: Under rainfed conditions, the UR2N1+QL14 combination effectively balances the trade-off between grain yield and environmental impact, and is therefore recommended as an optimal fertilization-cultivar strategy for rainfed maize production in Northwest China.
