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

The emergence of ferroelectricity in doped aluminum nitride has positioned wurtzite nitrides as promising candidates for next-generation memory and logic devices. However, the structural modifications required to induce and stabilize ferroelectricity, including changes in bond strength, harmonicity, and crystal order, also affect phonon dynamics, creating competing pathways for polarization reversal and thermal transport. In this work, we report the contrasting roles of dopants in governing ferroelectric and thermal properties in Al
