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
Multifunctional polyurethanes face a fundamental design trade-off: enhanced cross-linking and rigidity improve mechanical robustness but inevitably restrict chain mobility, thereby compromising essential features such as self-healing and recyclability. This inherent compromise severely constrains their multifunctional application. Here, we report a supramolecular polyurethane (COPUSL) comprising a "dynamic switch" constructed from dynamic disulfide bonds and hydrogen bonds, together with a "rigid-flexible balanced network" composed of castor oil long fatty chains and polyphenol-functionalized lignin. This design endows COPUSL with excellent mechanical properties while also enabling rapid self-healing (self-healing efficiency: 87%) and efficient recyclability. Furthermore, COPUSL with introduced aromatic structures and extended conjugate systems exhibits 100% ultraviolet-blocking efficiency and a high photothermal conversion capability (surface temperature: 153 °C) due to the electron transition and energy release of the lignin structure after absorbing light energy. By systematically investigating the relaxation kinetics, dynamic behavior, and macroscopic properties, we elucidate the distinct roles of the "dynamic switch" and "rigid-flexible balanced network" in regulating the polymer architecture and connecting dynamic behavior with mechanical and functional performance. These findings provide molecular-level insights for the design of high-performance, bio-based polyurethane with tailored multifunctional responsiveness.
