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 efficient and stable blue emission remains a central challenge in the development of donor-acceptor-type thermally activated delayed fluorescence (TADF) materials. Charge transfer in TADF molecules typically occurs via either noncovalent through-space interactions or covalent through-bond interactions, with control over electronic coupling key to enabling effective TADF. Through-space charge transfer (TSCT), enabled by spatially proximal, face-to-face donor-acceptor architecture, offers an appealing approach to regulating charge-transfer excited states. Here, we propose an effective strategy for blue TADF molecules that leverages a multichannel TSCT approach to enhancing reverse intersystem crossing while suppressing donor-acceptor bond cleavage. Organic light-emitting diodes (OLEDs) based on the designed molecule exhibit blue emission at 468 nanometers, a high external quantum efficiency (EQE) of 32.3% with minimal roll-off, and exceptional operational stability with a
