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

Optical patterning of quantum dots is essential for the fabrication of light-emitting diodes displays. However, current patterning methods either require inert environments or compromised quantum dots optical properties under ambient conditions. Here, we report a photoresist-free strategy enabling direct quantum dot patterning in air by using triphenylphosphine, a cost-effective, commercially available molecule that functions simultaneously as a surface ligand, photoinitiator, and oxidation protector. Under light exposure, triphenylphosphine reacts with atmospheric oxygen to trigger solubility changes, allowing precise patterning with resolutions up to 9534 dpi. The resulting devices exhibit external quantum efficiencies of 21.6% (blue), 25.6% (green), and 20.2% (red). We further demonstrate full-color active-matrix quantum dots light-emitting diodes displays by integrating the patterned red, green and blue quantum dots with thin-film transistor backplanes. This work offers a scalable, non-destructive, and environmentally compatible patterning solution for industrial display technologies.
