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
In recent years, cases of resistance to major antifungal drugs have been reported for Candida species. The growing resistance of fungi to conventional antifungal agents demands the development of new and effective antifungal strategies. Organosolv lignin-capped silver-based nanoparticles constitute a promising strategy, combining the antifungal activity of metallic silver with the biocompatibility and sustainability of organosolv lignin. In this context, we report a fast green photochemical method for synthesizing plasmonic silver/silver chloride nanoparticles capped with organosolv lignin (OL/Ag/AgCl-NPs) for antifungal applications. The OL/Ag/AgCl-NPs possess a well-defined spherical three-layered architecture, comprising a semiconductor AgCl core, an intermediate metallic silver surface, and a thin outer organosolv lignin layer. The cytotoxicity of the OL/Ag/AgCl-NPs in VERO cells was confirmed to be concentration-dependent. Crucially, cells exposed to toxic doses recovered metabolic activity comparable to controls, suggesting potentially reversible cytotoxic effects. The broad-spectrum antifungal agent Amphotericin B (AmB) effectively inhibited the growth of pathogenic Nakaseomyces glabratus (formerly Candida glabrata) and Pichia kudriavzevii (formerly Candida krusei), both displaying a minimum inhibitory concentration (MIC) of 0.19 µg/mL. In contrast, pathogenic Candida tropicalis exhibited resistance to AmB. Notably, OL/Ag/AgCl-NPs exhibited remarkable antifungal activity against N. glabratus, P. kudriavzevii, and AmB-resistant C. tropicalis, with MIC values of 1.09 µg/mL, 2.18 µg/mL, and 2.18 µg/mL, respectively. Moreover, the results revealed that the OL/Ag/AgCl-NPs exhibited a fungistatic effect against N. glabratus and P. kudriavzevii, while exhibited a fungicidal effect against the AmB-resistant C. tropicalis. These findings are particularly relevant given the challenge of treating resistant fungal infections and may contribute to the development of new therapeutic strategies. This study advances organosolv lignin-based nanomaterials, offering a promising platform for future biomedical applications.
