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

Developing sustainable adhesives with simultaneous high adhesive strength and excellent work of debonding remains challenging. Here, strong, ultra-tough, environmentally reliable, and recyclable polyurethane adhesives are reported, utilizing a multiscale engineering approach. The multiscale structure employs a top-down design philosophy to merge the advantages of both thermoplastic and thermosetting systems, integrating multi-level organizations including macroscale dual-length dynamic crosslinked networks, mesoscale initial and fibrillar crystals, nanoscale hard phase domains, and molecular scale weak hydrogen bonds. The multiscale structure exhibits the following features: multi-level organizations and surface-anchored high energy phases significantly enhance the bulk cohesion and interfacial adhesion, respectively. And hydrophobic organizations provide barrier mechanisms, while dynamic crosslinking enables network reconfiguration. As a result, the developed adhesive exhibits both high adhesive strength (21.24 MPa) and ultrahigh work of debonding (35,731 N m
