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
backgroundGreen synthesis of selenium nanoparticles (SeNPs) using Ferula assa-foetida L. root extract offers an eco-friendly approach for biomedical and agricultural applications by leveraging plant metabolites. This study characterized SeNPs, evaluated antimicrobial and antioxidant properties of the extract and SeNPs, assessed SeNPs’ biostimulant effects on Vicia faba L. seed germination, and explored bioactivity mechanisms via molecular docking.
resultsSeNPs, averaging 90.4 nm, were characterized using UV-Vis spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, transmission electron microscopy (TEM), zeta sizer, and zeta potential. SeNPs exhibited notable antimicrobial activity against Escherichia coli, Staphylococcus aureus, and Candida albicans. Inhibition zones were: E. coli (SeNPs: 18 mm; extract: 15 mm), S. aureus (SeNPs: 15 mm; extract: 12 mm), and C. albicans (SeNPs: 13 mm; extract: 17 mm). Molecular docking linked these to SeNPs’ binding to E. coli RNA polymerase (3LU0, -3.3224 kcal/mol), S. aureus RNA polymerase (4EDG, -3.0732 kcal/mol), and C. albicans CYP51 (5FSA, -3.5097 kcal/mol), indicating transcription and fungal membrane disruption. The extract exhibited strong antioxidant capacity via DPPH assay (IC50: 37.38 µg/mL), while SeNPs showed moderate activity (IC50: 338.4 µg/mL), correlated with superoxide dismutase binding (2SOD, -2.0912 kcal/mol), enhancing radical scavenging. Seed priming with low SeNP concentrations (1 and 5 µM) increased Vicia faba shoot length (56.66%, 30%) and root length (4 to 8.5 cm at 5 µM), with elevated sugars (57.06% at 1 µM) and proteins (33.1% at 1 µM), tied to auxin receptor TIR1 binding (2P1Q, -3.3108 kcal/mol), promoting growth signaling.
conclusionFerula assa-foetida extract and SeNPs demonstrated antimicrobial efficacy against multidrug-resistant pathogens, with the extract’s phytochemicals supporting green SeNPs synthesis. SeNPs outperformed the extract against E. coli and S. aureus, while the extract excelled against C. albicans. Low SeNP concentrations enhanced Vicia faba growth, promising for agriculture, but high doses inhibited growth, requiring caution. Molecular docking suggested mechanisms needing validation. Further phytochemical studies were recommended for medical and agricultural applications, pending clinical testing.
