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

Oxide-ion solid electrolytes are enabling components for high-temperature electrochemical technologies, including batteries, fuel cells, membrane reactors, sensors, and electrolyzers. The long-standing challenge is the thermal-expansion-coefficients (TECs) mismatch between electrolytes and adjacent device components over broad operating temperature windows. Here, we demonstrate a design paradigm of phonon-driven negative-thermal-expansion (NTE) framework can be leveraged not only to suppress thermal expansion but also to activate interstitial oxide-ion migration through collective tetrahedral tilts. As a proof of concept, we report the first demonstration of interstitial oxide-ion conduction in La-doped flexible phenacite-type NTE Zn
