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: Optimizing planting density and nitrogen application rate are key factors for increasing maize yield, but they also significantly affect farmland CO Methods: A field experiment was conducted to investigate the effects of planting density and nitrogen rate on soil CO Results: The results showed that soil respiration rate exhibits a distinct unimodal curve, reaching its maximum during the maize flowering stage, and showed a highly significant positive correlation with soil temperature. Soil CO Conclusion: In conclusion, applying nitrogen at approximately 270 kg ha
