Multifunctional Self-Pumping Janus Dressing for Exudate Management and Diabetic Wound Healing.
Article in Biomolecules, 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
Diabetic chronic wounds are often accompanied by excessive wound exudate maceration, which prolongs the inflammatory phase and increases the risk of infection. Such a complex wound microenvironment imposes more stringent requirements on multifunctional wound dressings. A multifunctional Cur Janus nanofibrous dressing is developed by integrating an electrospun poly(ε-caprolactone)/gelatin hydrophilic layer with a curcumin (Cur)-loaded PCL hydrophobic layer. Janus structure with asymmetric wettability, which exhibited unidirectional liquid transport properties both in vitro and in vivo. Its unique structure also makes it possible to carry both hydrophilic and hydrophobic drugs at the same time. The incorporation of curcumin endows the dressing with antibacterial and antioxidant functionalities, offering the potential to modulate the inflammatory microenvironment of diabetic chronic wounds. Furthermore, the wound healing ability and anti-inflammatory effects of Cur Janus nanofibers were evaluated in a diabetic mouse model. The results showed that Cur Janus nanofibers significantly reduced wound area, increased the proportion of pro-healing M2 macrophages, shortened the inflammatory phase, and ultimately accelerated diabetic wound healing. This work provides a multifunctional and scalable platform for advanced wound dressing design. Its excellent antibacterial, antioxidant (ROS scavenging) and anti-inflammatory (macrophage phenotype M1 to M2) properties, combined with the unidirectional fluid transport and dual-release potential of hydrophilic and hydrophobic drugs, demonstrate broad prospects in the management of diabetic wounds.
