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

Gallium-based liquid metals (GBLMs) are widely used in soft machines and stretchable electronics, but their nanometer-thick surface oxide layer induces strong adhesion to substrates, making residue-free removal challenging. Conventional methods rely on harsh chemical treatments, limiting practical applications. Here, we show that the oxide layer of eutectic gallium-indium (EGaIn) can be cleanly peeled from a substrate when a sufficiently large contact angle is maintained during slow delamination. Through experimental and theoretical analysis, we show that peeling fails at small contact angles due to mechanical fracture of the oxide skin at the oxide-air interface, leaving behind residue. By examining the contact line at the nanoscale, we identify the failure mechanism governing this process. This work provides fundamental insights into the interfacial mechanics of GBLMs and establishes a framework for improving their controllability in liquid metal-based technologies.
