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

Colloidal quantum well-based light-emitting diodes are highly promising for electroluminescent applications owing to their high fraction of horizontally aligned transition dipole moments, but scalable fabricating their films with dominant horizontal dipole orientation for electroluminescent devices remain major challenges. Here, we utilize a two-phase driving flat arrangement strategy combined with Langmuir-Schaefer technology to create compact colloidal quantum well films with predominantly horizontal dipole alignment. The interfacial driving force between the two liquid phases facilitates the formation of uniform, densely packed films, which exhibit 90% horizontal dipole alignment, yielding a light extraction efficiency of 35.8%. The resulting devices achieve (4 mm
