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

Spiral growth in two-dimensional (2D) materials has conventionally been explained by single screw dislocation mechanisms, yet a complete multiscale understanding remains elusive due to the intricate nature of screw dislocation structures. Here, we present a stabilization approach through metallic transition metal dichalcogenides (m-TMDs) overlayers on spiral semiconducting TMDs (s-TMDs), which enables unprecedentedly robust atomic-resolution imaging of screw dislocations in cross-sectional van der Waals heterostructures. Our multiscale investigations identify nanoscale substrate undulations as critical nucleation sites for screw dislocations and uncover a multi-screw dislocation-driven (MSDD) growth paradigm, characterized by periodic stress stripes with linear densities approaching ∼10
