Reproducible Fabrication of a Chamber for Birefringence Imaging: Experimental Test with Temperature-Controlled Liquid-Crystalline DNA Assemblies.
Article in ACS omega, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Liquid-liquid-crystalline phase separation (LLCPS) is an emerging class of soft-matter organization in which liquid-liquid phase separation couples with ordering. Quantitative birefringence imaging offers a powerful tool to characterize the resulting anisotropic condensates; however, reproducible measurements require sealed, evaporation-resistant chambers compatible with polarization optics. In this study, using a partially mechanized process, a simple glass-polydimethylsiloxane-glass chamber was fabricated that ensures reproducible sealing and minimizes user-dependent variability. The chamber maintained its structural integrity during multiple heating/cooling cycles, enabling the stable observation of liquid-crystalline DNA assemblies as a model LLCPS system. Abundant quantitative information was obtained from the observed birefringence characteristics, demonstrating the suitability of the chamber for quantitative analysis under controlled conditions. This versatile platform enables easy customization of surface chemistry and geometry, providing a practical foundation for future optical studies of diverse LLCPS and related soft-matter systems.
