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

Strain engineering of 2D heterostructures is pivotal for next-generation flexible electronics. Here, we investigate the straintronic and spintronic properties of MnO₂/SiC van der Waals heterostructures (vdWHs) using density functional theory (DFT). Our results reveal: (i) a strain-induced transition from Type-I to Type-II band alignment, (ii) emergence of topological signatures under tensile strain, and (iii) enhanced visible-light absorption. The MnO₂/SiC vdWH, with its intrinsic ferromagnetism (4.85 µB) and strain-tunable multitronic responses, offers a unique platform for spintronic and optoelectronic applications unattainable in conventional TMD-based systems.
