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
Fusarium culmorum is a soil-borne fungal pathogen causing root and stem rot, seedling blight, and significant yield losses in small grain cereals, including wheat. This study aimed to evaluate the antifungal potential of Bacillus subtilis ED24, an endophytic strain isolated from Ziziphus lotus (L.) roots, and its effects on wheat growth and yield under controlled conditions. In vitro assays demonstrated that B. subtilis ED24 inhibited F. culmorum mycelial growth by up to 87%, associated with the secretion of 37 distinct secondary metabolites, predominantly involved in carbon cycling. In pot experiments, B. subtilis ED24 significantly enhanced wheat germination (85%) and growth compared to infected plants treated with the chemical fungicide tebuconazole. Although nutrient analysis showed significantly higher shoot nitrogen (32.34 mg/pot) and phosphorus (2.41 mg/pot) contents in the B. subtilis ED24 treatment compared to tebuconazole (8.11 and 0.18 mg/pot, respectively), no significant differences were observed when compared to the infected control (C-). Similarly, B. subtilis ED24 led to improved thousand grain weight (40.4 g), protein content (19.98%), and ash content (1.95%) relative to tebuconazole (29.1 g, 18.31%, and 1.74%, respectively), yet these values did not differ significantly from the infected control (C-). Notably, the number of seeds per pot was significantly increased by B. subtilis ED24 compared to the infected control (C-) (113.8 seeds/pot vs. 54.2 seeds/pot). Additionally, B. subtilis ED24 modulated the wheat rhizosphere microbiome, enriching beneficial taxa such as Eurotiomycetes fungal class and the bacterial genus Paramesorhizobium. These findings suggest that the antifungal activity and growth-promoting effects of B. subtilis ED24 are likely mediated through the synthesis of unique bioactive metabolites and microbiome modulation, offering a promising sustainable alternative to chemical fungicides in wheat production.
