Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Developing novel nanofibrous skin substitutes using biomaterials that exhibit biocompatibility, suitable mechanical strength, and inherent antibacterial activity is essential. In this study, we fabricated polyvinyl alcohol/tragacanth gum/polyaniline (PVA/TG/PANI) nanofibrous membranes via co-electrospinning of PVA/TG and PVA/PANI. The membranes were characterized using scanning electron microscopy, contact angle measurements, swelling tests, and mechanical examination. The co-electrospun nanofibers achieved an average fiber diameter of 176.45 ± 29 nm. Contact angle measurements confirmed the hydrophilicity of these membranes, which also exhibited favorable mechanical properties, including sufficient strength and flexibility. Cytocompatibility was assessed by culturing HDF-4 cells; the co-electrospun PVA/TG/PANI membrane demonstrated the highest cell viability at 91.94%, surpassing that of PVA/TG nanofibers. Furthermore, antibacterial activity against E. coli and S. aureus was significantly enhanced in the co-electrospun nanofibers compared to the PVA/TG and PVA/PANI counterparts. Based on these findings, we propose the co-electrospun nanofibrous membrane as a promising scaffold candidate for skin tissue engineering applications.
