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

From strong shear thickening (ST) to jamming, conventional shear thickening fluid (STF) systems have been thoroughly explored in the past few decades. A picture from hydrodynamics to lubrication breakdown and interparticle friction has been unveiled and verified in various studies for conventional STF systems. This work presents a well-studied ionic liquid-based shear thickening fluid (ILSTF) in an unexplored field of jamming dynamics, which demonstrates a lubricated nature not only in strong shear thickening, as characterized by the rheology test, but also in the jamming and even solidification process triggered by dynamic normal impact. A well-fitted Modified Added Mass Model is built for jamming with the solid boundary, based on the classical Impact-Activated Normal Solidification (IANS) framework. Impact jamming front propagates with a few nanometers' thickness solvation layer lubricating the silica nanoparticles, before it decreases due to the squeezing induced by the gradual compression of increasing stress level on the jammed zone. This can be classified as a progressive jamming realm.
