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

From a molecular perspective, chirality is manifested in the intrinsic asymmetry of atomic arrangements that cannot be superimposed on their mirror images. Achiral molecules at nanometer scale can be assembled to have micron-scale chiral structures using physical stimuli, but the resulting chiral structures are often spatially limited, difficult to control over large areas, or unstable once the stimulus is removed. Here we show that a confined anisotropic molecular medium, derived from the nematic mesophase, undergoes a field-driven symmetry-breaking transition that generates micron-scale chiral structures. This approach provides a simple and scalable route to generate macroscopic chiral optical materials from molecularly symmetric precursors.
