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

Perovskite light-emitting diodes (PeLEDs) have achieved remarkable progress in recent years, with green-emitting PeLEDs now exhibiting external quantum efficiencies (EQEs) exceeding 30%, rivaling those of organic light-emitting diodes (OLEDs). While quasi-2D perovskite structures have emerged as a promising strategy for high-efficiency PeLEDs─owing to their enhanced exciton binding energies and charge carrier confinement─their phase distribution remains a critical yet challenging factor governing device performance. In this study, we demonstrate that the phase distribution in quasi-2D perovskite films is highly sensitive to the solvent atmosphere during annealing. Polar solvents (e.g., dimethylformamide, dimethyl sulfoxide) introduce nonradiative recombination centers and accelerate film decomposition, whereas nonpolar solvents (e.g., chlorobenzene) suppress degradation and promote high-
