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

Circularly polarized light-emitting diodes hold great promise for advanced photonic applications such as three-dimensional displays, quantum information processing, and optical spintronics. Carbon dots, owing to their metal-free nature, high stability, and structural versatility, have emerged as attractive alternatives. However, their intrinsic chirality is typically weak due to a lack of precise control over structure and molecular arrangement, and their application in electroluminescent devices has remained unrealized. Here, we report a class of supramolecular assemblies consisting of fluorinated π-conjugated carbon dots. Upon interaction with M/P-[N] hexahelicene as chiral inducers, a directed supramolecular self-assembly is formed via strong electrostatic and hydrogen bonding interactions, yielding a high absorption dissymmetry factor of up to 0.107. More significantly, we demonstrate the devices based on these supramolecular assemblies, achieving a maximum luminance of 9655 cd m
