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

Existing polymer materials often lack the ability to dynamically adjust lubrication in response to external stimuli. This gap in adaptable lubrication technology limits their application in advanced systems such as intelligent motion devices and soft robotics. To address this challenge, a dual-responsive lubricating hydrogel is introduced designed with a thermal and shear-responsive supramolecular network integrated into a stable polymer framework. The hydrogel exhibits a partial gel-sol transition under thermal or shear stress, mimicking the mucus secretion behavior of hagfish. As a result, the hydrogel's surface secretes a liquid supramolecular layer that significantly alters its coefficient of friction (COF), achieving up to a 20-fold reduction in friction due to the reversible supramolecular transition. This hydrogel demonstrates significant potential as an intelligent lubrication material capable of dynamically responding to varying stimuli, paving the way for more adaptive and efficient lubrication technologies.
