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

This work presents a facile one-pot synthesis strategy for highly strong and tough eutectogels. The exceptional mechanical performance (average stress: 3.8 MPa; average strain: 920%) stems from synergistic trivalent aluminum(III)-ligand coordination crosslinking and extensive hydrogen bonding within the network. The optimized proportion has achieved a balance between mechanical stress and strain. Reversible bonding enables rapid energy dissipation and elastic recovery. A flexible strain sensor fabricated from this eutectogel demonstrates high sensitivity (gauge factor > 2) and ultrafast response (200 ms), validating its potential as low-cost electronic skin. This research provides a foundational framework for developing sustainable, high-performance flexible.
