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

Organoboron narrowband emitters leveraging the multi-resonance (MR) effect have emerged as key material components for wide-color-gamut organic light-emitting diodes (OLEDs) that offer high efficiency and excellent color reproducibility. However, conventional MR-type thermally activated delayed fluorescence (MR-TADF) emitters suffer from severe efficiency roll-off in OLEDs operated at high brightness due to slow reverse intersystem crossing (RISC). Here, we report the first MR-TADF emitters incorporating tellurium (Te)-the heaviest stable chalcogen-to accelerate the spin-flip RISC process through enhanced spin-orbit coupling. Our design strategy involves tethering dibenzo[b,d]tellurophene as a RISC booster to a representative MR skeleton, thereby promoting efficient delayed fluorescence. The resulting Te-containing MR-TADF emitters exhibit fast RISC rates of up to 2.8 × 10
