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

Quantum dots are promising candidates for more efficient and brighter light-emitting diodes in display and lighting applications. However, due to low carrier concentrations and strong confinement, the electroluminescence efficiency and brightness are hindered by low exciton formation rate, i.e. the probability of electrons meeting holes. Here, we demonstrate that the weak hole confinement, induced inter-dot hole diffusion in quantum dots with large CdZnSe cores and thin ZnS shells, allows more efficient exciton formation. As a result, we achieve a peak external quantum efficiency of 30.7%, a maximum luminance exceeding 1.9 million cd m-2 in green quantum dot light-emitting diodes. Moreover, efficient utilization of carriers depresses the Joule heat generation, allowing us to achieve a T95 operational lifetime (time for the luminance to decrease to 95% of the initial value) of 21,900 hours at 1000 cd m
