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
backgroundChronic, epidermal full-thickness wounds present a critical clinical challenge due to high risks of infection, impaired healing, and lack of advanced dressings that synergistically combine antibacterial efficacy with tissue regeneration.
objectiveThis study aims to design and evaluate a multifunctional nanofibrous scaffold that simultaneously addresses anti-infection, mechanical support, and controlled tissue remodeling.
methodsA tri-component nanofibrous scaffold composed of polyvinyl alcohol, chitosan, and polycaprolactone was fabricated via electrospinning. Selenium nanoparticles (SeNPs) were incorporated to impart antibacterial and pro-healing properties. The scaffold was characterized for morphological, mechanical, and biological attributes. In vivo performance was assessed using a murine epidermal full-thickness wound model.
resultsThe scaffold demonstrated significantly enhanced mechanical properties and exhibited potent antibacterial activity against S. aureus and E. coli. Controlled release of SeNPs reduced initial cytotoxic burst effects. In vivo tests confirmed accelerated wound closure and superior tissue regeneration compared to controls
conclusionThe SeNP-functionalized nanofibrous scaffold represents a promising therapeutic platform for epidermal full-thickness wound healing, effectively combining mechanical robustness, antibacterial action, and biocompatibility.
