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 high-performance underwater adhesives capable of tolerating complex application scenarios while exhibiting specific degradability represents a critical yet highly challenging endeavor. Inspired by marine bio-adhesion, this work reports a catechol-ammonium cation synergistically reinforced poly-(disulfides) underwater adhesive, which demonstrates universal adhesion across diverse substrates and especially robust adhesion stability across a wide temperature range, spanning from -196 °C to 200 °Ca feature rarely reported in dynamic polymeric systems. Such exceptional stability is attributed to the synergistic integration of π-cation interactions, covalent crosslinking, and multiple hydrogen bonds in the cohesive network. More importantly, the adhesive exhibits self-reinforced in situ underwater adhesion, reaching a maximum strength of 7 MPa on glass substrates. This unique self-reinforcing behavior stems from the capacity of cationic amine groups to displace substrate hydration layers, thereby creating a dehydrated interface favorable for catechol-mediated binding. Meanwhile, the hydrophobic poly-(disulfides) backbone effectively impedes water penetration, endowing the adhesive with long-term underwater stability. Moreover, the inherently dynamic poly-(disulfides) backbone undergoes specific depolymerization in alkaline conditions, thereby expanding the potential applications of this high-performance, degradable underwater adhesive in complex aqueous and even marine environments.
