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
The advantages of molecular ferroelectrics lie in the "designability" and "multifunctionality", and the molecular-level regulation ability has opened up a brand-new dimension for ferroelectric materials. Non-covalent interactions play a crucial role in the construction of molecular ferroelectrics. However, there remain significant challenges in balancing the strength and reversibility of non-covalent interactions, as well as achieving long-range ordered arrangements. Therefore, a systematic study of non-covalent interactions in the structure is the key to construct high-performance molecular ferroelectrics. Here, we introduced halogenated amines with large dipole moments into adjacent inorganic layers to regulate the non-covalent interactions in the structure, thereby inducing the generation of ferroelectricity.
