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

Ferroelectric vortices have received much attention in the past decade due to their functionalities and potential applications in nanoelectronics. However, most of the vortices fabricated in the nanoislands have a size of more than a hundred nanometers, which limits the miniaturization of electronic devices. Here, we show the realization of a high-density vortex lattice with ~10- to 20-nanometer size in ultrathin bismuth ferrite/barium titanate bilayer by strain engineering. The obtained vortex shows a nested structure, e.g., an outer center-type structure with a nested inner ring included, which is well supported by piezoelectric force microscopy, transmission electron microscopy, and phase-field simulations. The nested vortex structure is not only more stable than the center-type vortex structure but also exhibits controllable multistate conduction with low energy consumption (<100 zeptojoules, e.g., 10
