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.

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
backgroundFenugreek is a widely used aromatic herb valued as a food ingredient. Fenugreek seeds and leaves are rich in antioxidants and bioactive compounds that support overall health, particularly gastrointestinal function. The present paper describes a green synthesis of silver nanoparticles (AgNPs) utilizing aqueous and ethanolic extracts of fenugreek seeds (
methodsFT-IR, High-Resolution Transmission Electron Microscopy (HRTEM), DLS, and zeta-potential were used to characterize the produced AgNPs, aiming to verify their stability, size distribution, and formation. The biological activities of these extracts are then compared.
resultsThe ethanolic extracts were more effective for producing smaller, more homogeneous, and relatively stable AgNPs compared to aqueous extracts. Differences in phytochemical composition, which have a direct impact on the nucleation, development, and stability processes of NPs, could be the reason for the observed variances between plant extracts. AgNPs (aqueous), originated from Bulgaria, exhibited the strongest spasmogenic activity under the applied experimental conditions. The biosynthesized AgNPs also showed a selective antifungal activity against
conclusionsFrom a biological perspective, all samples' fenugreek extracts had a minimal impact on gastrointestinal contractility, but the AgNPs derived from these extracts had a greater spasmogenic effect. These findings point to a combination that enhances both functional efficacy and bioavailability. The Bulgarian fenugreek aqueous extract produced AgNPs with the strongest spasmogenic activity of all the preparations examined. The results showed the potential of AgNPs from fenugreek seeds for biomedical applications.
