1 · What the graph read from it

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.

2 · The registry

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

The biological activity of silver-based antimicrobial agents is strongly influenced by the source and generation method of silver ions (Ag⁺); however, a direct comparison of their efficacy from different sources has not been previously reported. In this study, we systematically compared the antibacterial and anti-virulence effects of Ag⁺ derived from three sources: direct current (DC) electrolysis, silver nanoparticles (Ag-NPs), and silver nitrate (AgNO₃), standardized to 400 ppm. Electrolyzed Ag⁺ exhibited the strongest antibacterial effect, reducing viable counts of Pseudomonas aeruginosa and Staphylococcus aureus by 91.06% and 71.10%, respectively. It also caused substantial membrane disruption, reduced motility, and increased cellular leakage, as confirmed by SEM imaging, DNA and K⁺ ion leakage, and extracellular protein release. Furthermore, electrolyzed Ag⁺ most effectively suppressed key virulence factors, including biofilm formation, pigment production (pyocyanin, staphyloxanthin), and the activities of protease, esterase, and hemolysin. Despite identical Ag⁺ concentrations, the biological activity varied significantly with ion source, underscoring the importance of the delivery mechanism. These findings highlight the superior efficacy of electrolyzed Ag⁺ and support its potential application in clinical, environmental, and industrial antimicrobial strategies.
