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

Perovskite light-emitting diodes (PeLEDs) promise efficient, pure-color next-generation displays but suffer from charge injection imbalance due to energy barriers at the indium tin oxide (ITO)/perovskite interface. To address this, we introduce non-conjugated phosphorylated chitosan (NCPC) as an efficient hole injection layer (HIL) for the first time. NCPC enhances interfacial interactions with ITO and the hole-transport layer (HTL), effectively reducing their energy barrier and achieving favorable energy level alignment. This significantly lowers both charge injection barriers and interfacial nonradiative recombination. Incorporating NCPC markedly improves device performance. Red, green, and blue PeLEDs show maximum external quantum efficiency (EQE
