Methacrylated Chitosan Methacrylated Poly(vinyl alcohol)-Based Hydrogel Patch for Long-Term Electrochemical Wound pH Sensing.
Article in ACS sensors, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
While every wound has the potential to become chronic, the risk is significantly higher in individuals with specific medical conditions. Given this inherent risk, continuous wound monitoring patches are beneficial for all wound types throughout the healing process, enabling the early detection and management of chronic wound development. In this work, we introduce an eco-friendly, hydrogel-integrated, capillary-driven wound patch designed for continuous pH monitoring. The hydrogel, synthesized from methacrylated chitosan and methacrylated poly(vinyl alcohol), provides antibacterial properties, tissue adhesion, and moisture retention, thereby supporting stable electrochemical pH detection. A paper-based, capillary-driven microfluidic layer facilitates fluid transport toward an evaporation pad, enhancing liquid uptake by approximately 4-fold after 2 h compared to the hydrogel alone. In vitro experiments demonstrated that the hydrogel-integrated sensor effectively monitored pH, exhibiting a near-linear voltage response of 16.92 mV per pH unit. The implementation of such a wound dressing represents a significant advancement in wound healing applications, combining functionality with environmental sustainability.
