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

Tetragonal tungsten bronze (TTB) ceramics have emerged as promising candidates for dielectric energy storage due to their intrinsic multi-site architectures. However, the limited energy storage performance achieved so far remains insufficient for advanced electronic and pulsed power applications. Here, we propose a targeted polar-entropy regulation strategy via minor multi-element substitution at the polar-active B-sites, enabling precise modulation of polar displacements and weakened coupling among polar nanoregions. Atomic-scale characterization reveals site-dependent structural responses, which collectively reshape local polarization configurations and dipolar correlations. As a result, we demonstrate the feasibility of TTB ceramics for state-of-the-art multilayer energy-storage device applications, achieving an outstanding recoverable energy density (W
