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.
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
Realizing high electroluminescence dissymmetric factor and high external quantum efficiency at the same time is challenging in light-emitting diodes with direct circularly polarized emission. Here, we show that high electroluminescence dissymmetric factor and high external quantum efficiency can be simultaneously achieved in light-emitting diodes based on chiral perovskite quantum dots. Specifically, chiral perovskite quantum dots with chiral-induced spin selectivity can concurrently serve as localized radiative recombination centers of spin-polarized carriers for circularly polarized emission, thereby suppressing the relaxation of spins, Meanwhile, improving the chiral ligand exchange efficiency is found to synergistically promote their spin selectivity and optoelectronic properties so that chiroptoelectronic performance of resulting devices can be facilitated. Our device simultaneously exhibits high electroluminescence dissymmetric factor (R: 0.285 and S: 0.251) and high external quantum efficiency (R: 16.8% and S: 16%), demonstrating their potential in constructing high-performance chiral light sources.
