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

Electrochromism encompasses phenomena where materials undergo color changes in response to electricity. Conventional understanding attributes electrochromism to redox reactions occurring between phases with distinct band structures. We report an unconventional electrochromic mechanism in boron arsenide (BAs) crystals that challenges this traditional paradigm. Upon application of several volts, these crystals exhibit rapid color transformation from transparent-red to black, reverting to original color upon voltage removal. Comprehensive structural characterization reveals that this color modulation originates from electromechanical effects rather than redox reactions. Specifically, the observed band gap narrowing stems from strain-induced charge symmetry enhancement within BAs. This discovery not only expands the fundamental understanding of electrochromic mechanisms but also establishes BAs as a unique semiconductor exhibiting exceptional physical properties beyond its reported thermal and electrical transport characteristics.
