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

Realizing air-processed blue halide perovskite films with tailored emission is significant for promoting the commercialization of perovskite light-emitting diodes (PeLEDs). However, the intrinsically inferior thermodynamic stability and laborious crystallization kinetics control under humidity interference limit the fabrication of blue perovskite emitters in ambient air. Here, air-processed pure-bromide quasi-2D blue perovskite films are achieved with stabilized lattice and tunable emission by interstitial doping of trivalent metallic cations. This strategy improves the formation energy of the perovskite lattice, promotes energy transfer between different n phases, and suppresses intrinsic electron-phonon coupling in the perovskite films. The emission-controllable blue PeLEDs are fabricated in ambient air for the first time. The champion deep blue PeLED shows maximum external quantum efficiency (EQE) of 2.05% and luminance of 246.56 cd m
