The cylindrical devices with tunable positive, infinite, and negative capacitance for dynamic random access memory.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Due to a stray field formation from the alternating ferroelectric bound charges of the multidomain state of the ferroelectric thin films, the negative capacitance effect can emerge in the ferroelectric/dielectric bilayer devices. However, the capacitance behavior of the thin ferroelectric/dielectric stacked films in the nanoscale cylindrical structure deviated from the negative capacitance state to unpredicted other states. This work confirmed that the thin (2.0 - 3.0 nm) ferroelectric Hf
