Article in Advanced materials (Deerfield Beach, Fla.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Achieving nondestructive, high-resolution patterning of perovskite nanocrystals (PeNCs) is essential for next-generation near-eye displays. However, the intrinsic instability of PeNCs renders conventional patterning methods detrimental to their optical and electrical properties. Herein, a dual strategy is reported that enables both high-resolution patterning and the fabrication of efficient light-emitting diodes (LEDs). The first strategy involves an advanced direct photocatalytic patterning method. Thiol crosslinkers are systematically investigated and identified 1,8-octanedithiol and 1,10-decanedithiol as optimal candidates due to their solvent compatibility, colloidal stability, and ability to achieve nondestructive patterning with high resolution and fidelity. The second strategy introduces a film-state ligand exchange (FLE) process to enhance the optical and electrical properties of patterned PeNC films. Replacing long-chain ligands with short-chain ammonium halides results in denser surface passivation and enhanced charge transport capability. Dual strategy enabled high-performance crosslinked PeNC-LEDs, including a maximum external quantum efficiency of 14.7% and luminance of ≈25,400 cd m
