Ovicidal effect of eucalyptus wood vinegar on gastrointestinal nematodes' eggs from sheep.

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
Background and Aim: Gastrointestinal nematodes (GINs) significantly impair small ruminant production globally, particularly in tropical regions. Anthelmintic resistance due to the indiscriminate use of synthetic drugs has necessitated the search for sustainable, plant-based alternatives. Eucalyptus wood vinegar (WV), a by-product of biomass pyrolysis, possesses bioactive compounds with potential anthelmintic activity. This study aimed to assess the Materials and Methods: WV samples were produced through controlled pyrolysis and refined through sequential vacuum distillation. Egg hatchability tests were performed using five WV concentrations (0.3125%-5% g/100 mL), with thiabendazole as a positive control and distilled water as a negative control. Egg counts, species identification, and scanning electron microscopy (SEM) were conducted to evaluate structural changes. The chemical compositions of the WVs were characterized using gas chromatography-mass spectrometry (GC/MS). Results: Both WVs exhibited significant ovicidal activity, with eucalyptus WV achieving 97% inhibition at 1.25%, and the marjoram-enriched WV reaching 100% inhibition at 5%. GC/MS analysis revealed the presence of phenolic compounds, furfural, thymol, and eucalyptol, the latter two being exclusive to the marjoram formulation. SEM micrographs confirmed morphological deformations in treated eggs, including loss of symmetry and membrane integrity. The synergistic interaction among bioactive components, particularly thymol, eucalyptol, and furfural, is proposed as the mechanism enhancing ovicidal activity. Conclusion: Eucalyptus WV, particularly when enriched with
