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

B,N-doped nanographenes are promising blue OLED dopants owing to their narrowband emission and triplet-exciton harvesting capability, but their inefficient reverse intersystem crossing (RISC) remains a bottleneck for practical applications. Although π-extension is widely used to accelerate RISC and improve color purity, the role of molecular topology remains unclear. Here we report three deep-blue, quadruple-borylated nanographenes with isomeric skeletons and topology-dependent conformations ranging from negatively curved to quasi-planar. Combined theoretical and experimental studies reveal that enhanced planarity can facilitate the resonance effect, promote charge-transfer delocalization, and increase structural rigidity. Consequently, the most planarized emitter achieves an ultranarrow emission bandwidth of 13 nm/0.07 eV and a high RISC rate constant of 2.7 × 10
