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

Moiré superlattices formed in van der Waals heterostructures by twisting, lattice mismatch and strain present an opportunity for creating metamaterials with unique properties absent in the individual layers. Ferroelectricity for example, arises from broken inversion symmetry in twisted and strained bilayers of 2D semiconductors with stacking domains of alternating out-of-plane polarization. However, the individual contributions of twist and strain to the formation of topological polar nanostructures remain unclear and experimentally challenging to resolve. Inversion symmetry breaking is predicted to generate in-plane polarization along the domain walls, forming topologically non-trivial Bloch-type merons (half-skyrmions) in twisted systems and Néel-type merons in strained systems. Here we utilize angle-resolved vector piezoresponse force microscopy to spatially resolve polarization components and topological polar nanostructures in marginally twisted bilayer WSe
