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
Nucleation of the phase transition in liquid crystals (LCs) is influenced by elastic distortions around topological defects. While conventional studies have focused on isotropic-LC transitions upon cooling, nucleation in chiral LCs is investigated using colloidal arrays produced by capillarity-assisted particle assembly (CAPA) upon heating to spatially control the nucleation of the isotropic phase rather than that of the LC phase, enabling the fabrication of chiral pinwheel arrays. Optical analysis and Landau-de Gennes simulations reveal that pinwheel arrays arise from the interplay of LC chirality, planar anchoring conditions at the isotropic-LC boundary, and boojum defects on the particles. By manipulating particle placement and employing photopolymerizable LCs, dual alternating chiral and stabilized pinwheel arrays are realized. This work provides insights into chirality-driven phase transitions upon heating and offers a new strategy for designing LC materials with controlled anisotropic and chiral architectures.
