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

Achieving pure-green organic light-emitting diodes (OLEDs) with both precise spectral positioning and an ultra-narrow full-width at half-maximum (FWHM) remains highly challenging, as red-shifting emission into the pure-green regime is often accompanied by enhanced excited-state relaxation and spectral broadening. Herein, we report a molecular design strategy that reconciles green-region red-shift with intrinsic spectral narrowing through the synergistic integration of dibenzofuran fusion and cyano decoration within a meta-diboron framework. The proof-of-concept molecule DBFCN exhibits intrinsically ultra-pure green emission in dilute toluene, centered at 519 nm with a very small FWHM of 12 nm, placing it among the narrowest green multi-resonance thermally activated delayed fluorescence (MR-TADF) emitters reported so far. The bottom-emitting OLEDs deliver a maximum external quantum efficiency (EQE
