Fungal wood-degrading enzymes in esca-diseased grapevine and effects of carbohydrate environment on fungal development.
Article in Archives of microbiology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
In esca disease affecting grapevines, Phaeomoniella chlamydospora and Phaeoacremonium minimum colonize the woody parts of the trunks and arms, where they obtain nutrition from xylem sap and, potentially, from residues resulting from the enzymatic breakdown of lignified cell walls, particularly osidic residues. We quantified the secretion of lignin peroxidase, manganese peroxidase and laccase by these fungi in woody tissues of selectively infected cuttings using immunolabeling and transmission electron microscopy. Our results indicated that the detection of these enzymes was generally higher in tissues infected with Phaeoacremonium minimum. These data were confirmed through immunodetection of enzymes secreted by hyphae of fungi grown in vitro. Additionally, we observed that the supply of various carbohydrates (mono, di, tri and tetrasaccharides and polymers) differentially influenced fungal growth and polypeptide secretion. Since some secreted polypeptides display detrimental effects on grapevine cells, these results raise the question of whether the carbohydrate environment could be a factor affecting the aggressiveness of these pathogens.
