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

While trap states are traditionally considered as performance-limiting defects in organic light-emitting diodes (OLEDs), this work presents a dual-trap exciplex heterojunction system that strategically engineers trap states to enhance device performance. The tailored electron (4CzTPNBu in p-type host) and hole (PO-01 in n-type host) traps are employed for interfacial bidirectional carrier capture synergistically without compromising carrier transport in the exciplex heterojunction system. This innovative design converts interfacial traps into immediate radiative trap-assisted recombination (TAR) centers with significant expansion of exciton recombination zone, simultaneously preventing carrier transport imbalance and charge accumulation. The yellow OLEDs demonstrate cutting-edge 33.9% external quantum efficiency (EQE), and 453.6 h operational lifetime (LT
