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

Light emission from organic transistors holds strong potential for user-interactive functionality across applications ranging from wearable and biointegrated systems to neuromorphic electronics. However, conventional single-active-layer organic transistors suffer from inefficient charge carrier injection, resulting in high drain voltages (>80 V in field-effect devices and >3.5 V in electrochemical devices with p-i-n junctions) and narrow, spatially dynamic recombination zones (<75 μm). Here we report a single-active-layer electrochemical organic light-emitting transistor with drain-side electric double layer formation, achieving ultralow-voltage operation (<3.5 V) together with a wide, spatially pinned recombination zone. An ion transport enhancer in the light-emitting polymer channel induces an electric double layer at the drain electrode, overcoming limited electron injection without n-type doping. This mechanism enables flexible, large-area devices with a recombination zone width of 267 μm and a maximum luminance of 826 cd m
