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 combine fluidity with high thermal and electrical conductivity, making them attractive for lubrication in demanding environments. We investigated the tribological behavior of a Mo/Mo self-mated pair lubricated with Ga-In-Sn (GIS) from room temperature to 300°C in air and argon. Friction and wear tests, together with energy-dispersive spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) analyses, were used to examine interfacial behavior and tribofilm formation. In air, GIS reduced the Mo-disk wear rate by 90.9%-99.4% compared with the unlubricated pair, accompanied by the formation of a Ga-O-rich tribofilm. In argon, localized Ga retention, tribofilm delamination, and lamellar spalling became more pronounced at elevated temperature, leading to a wear rate of 15.6 × 10
