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

Iron homeostasis is critical for the survival of almost all organisms, yet its dysregulation is often caused by a synergistic effect of genetic and environmental factors. Previous studies have shown that trapping devices of the predominant nematode-trapping fungus (NTF) Arthrobotrys oligospora serve as an unprecedented iron sequestration system compensatory for lack of the crucial fungal vacuolar iron detoxification mechanism. Here, we found that among the Ascomycota phylum, only NTFs lacked gene coq7, which encodes COQ7 responsible for ubiquinol (UQ) biosynthesis and efficient iron chelation. Addition of exogenous UQ
