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: Many nitrogen-fixing bacteria (NFB) can synthesize siderophores. However, the contribution of NFB siderophore synthesis to plant growth has not been evaluated, and its impact on NFB's antifungal activity remains unclear. Methods: The type of siderophore synthesized by the nitrogen-fixing bacterium (NFB) Results: The strain GXGL-4A produces carboxylate-type siderophores. The antifungal ability of Δ Discussion: The loss of siderophore synthesis ability in NFB leads to a significant decrease in their ability to promote plant growth and their own antifungal capacity. By utilizing NFB with high siderophore production capability, it is expected to play a greater role in sustainable agricultural production.
