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

Metal halide perovskites have been successfully applied in a variety of fields such as LEDs, lasers and solar cells, thanks to their excellent optoelectronic properties. Capillary fibers can further expand the range of perovskite applications and at the same time improve its stability by encapsulating the perovskite inside the capillary. However, the high-quality perovskite film-coated hollow capillary fibers have yet to be realized. Here, we introduce a fast solvent exchange method which is used for the preparation of neat and smooth perovskite films deposited on the inner surface of capillary fibers. We demonstrate that this fast solvent exchange method is superior to the commonly used spontaneous diffusion-based precipitation method. The obtained hollow capillary fibers show a narrowed spectral width of 4.9 nm under pulse excitation due to the optical cavity effect. This new fabrication method can facilitate the development of perovskites in the fields of capillary lasing, microfluidic sensing, flexible LEDs and luminous fabrics.
