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

Fungal pathogens secrete cell wall-degrading enzymes that either act as virulence factors or are perceived by plants to trigger immunity responses. Stagonosporopsis cucurbitacearum causes gummy stem blight, a devastating disease affecting cucurbit crops worldwide. Here, we identified a lytic polysaccharide monooxygenase (LPMO) of the AA9 family, ScAA9, in S. cucurbitacearum and investigated its roles in fungal virulence and host immune manipulation. ScAA9 is a secreted protein that is highly expressed during early infection and contributes to full virulence but not growth, development and abiotic stress responses. The virulence role of ScAA9 is independent of its enzymatic activity. ScAA9 elicits cell death across various plant species, including cucurbit plants. This cell death-inducing ability does not require its LPMO activity and disulphide bonds but is determined by a 96-amino-acid fragment ScAA9
