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

Intrinsically stretchable light-emitting diodes (LEDs) are essential for next-generation wearable and implantable optoelectronics. However, achieving high-performance in intrinsically stretchable LEDs remains elusive due to the absence of a stretchable cathode that concurrently ensures efficient electron injection, mechanical compliance, and high optical reflectance. Here, we introduce a hybrid liquid metal-liquid metal particle (Hyb-LM) cathode, engineered by selective rupture of surface liquid metal particles (LMPs), which facilitates their transformation into a continuous liquid metal (LM) layer. The resulting bilayer structure, comprising a surface LM layer and an underlying LMP layer, exhibits an exceptional combination of low work function (∼4.1 eV), high reflectance (∼90%), low sheet resistance (2.70 × 10
