Broad-Spectrum Antibacterial Electrospun PCL-Silver Fibers Coupled with Chromogenic Hydrogel for Infection Sensing.
Article in Current microbiology, 2026. 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
Wound healing remains a significant clinical challenge due to susceptibility to bacterial infections, excessive oxidative stress and delayed cellular regeneration. The extensive and often indiscriminate use of antibiotics has further intensified the emergence of antimicrobial resistance. In this study, a multifunctional smart wound dressing is developed by integrating a chromogenic hydrogel with electrospun poly(ε-caprolactone) (PCL) fibers functionalized with quaternary ammonium moieties anchoring ionic silver. The PCL fibers functionalized with ionic silver provide antibiotic-free antibacterial properties, while the chromogenic hydrogel allows for real-time colorimetric detection of metabolically active microorganisms. The colorimetric assessment of the dressing in both in vitro and ex vivo environments has shown a distinct, time-dependent reaction to metabolically active bacterial populations. It has demonstrated outstanding cellular biocompatibility, increased cell viability in Vero cells, a notable decrease in oxidative stress, and enhanced cell migration in an in vitro scratch assay. This multifunctional dressing showcases a promising platform for advanced wound management applications by integrating antibacterial effects, real-time infection detection, and pro-regenerative cellular responses.
