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

Tandem light-emitting diodes (LEDs) offer advantages in efficiency, brightness and lower the current density for a target brightness, but their implementation in solution-processed perovskite LEDs is limited by interconnection strategies that introduce high voltage penalties and poor robustness. Here we demonstrate a hierarchically structured interconnection layer (ICL) integrating a near-degenerate charge-generation junction with a crystalline-amorphous oxide composite, enabling low-barrier transport and solvent-tolerant stacking with reduced loss. Using this ICL, we realize double-junction perovskite LEDs in which two subunits operate efficiently in series, achieving a peak external quantum efficiency (EQE) of 42.6%, a maximum radiance of 690 W sr
