1 · What the graph read from it

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.

2 · The registry

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

Polymer materials hold great promise for various applications but face trade-offs among stiffness, toughness, stretchability, and scalable fabrication. Here, we report a strategy that integrates dense side-chain hydrogen-bonding motifs capable of conformational transitions into a highly entangled flexible polymer network through photocuring copolymerization of acrylamide-based and hydroxyl-terminated acrylate monomers, enabling the rapid fabrication of stiff, tough, and stretchable polymers. The densely cross-linked structure restricts chain mobility, while hierarchical hydrogen bonds with partially low rotational energy barriers reversibly dissociate under strain, allowing the extensibility of the entangled network and continuous energy dissipation. The resulting polymers exhibit high Young's modulus (515.0 ± 100.9 megapascals) and yield strength (57.8 ± 1.8 megapascals) while maintaining exceptional toughness (135.7 ± 10.7 megajoules per cubic meter) and fracture strain (400.1 ± 46.1%) and full strain recovery upon heating. These polymers can be fabricated into complex structures via three-dimensional printing and exhibit shape-memory, impact-resistant, and adhesive properties. This work establishes a generalizable strategy for designing high-performance polymer materials through simple photopolymerization.
