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

The trihexagonal tiling system exhibits strong electron-electron interactions, positioning it as a key condensed matter platform for studying geometrically frustrated lattices made up of corner-sharing triangles. Its phase-transition-driven lattice modulations enable Fermi surface reconstruction, while emergent van Hove singularities near the Fermi level and correlated band anomalies present critical challenges in understanding electronic interaction mechanisms. By combining temperature-dependent spectroscopy, angle-resolved photoemission, and density functional theory calculations, we demonstrate a 61-fold enhancement in terahertz direct detection mode, ultra-low noise (1.38 × 10⁻²⁵ A²/Hz) below phase transition temperature, and broadband operation up to 100 GHz in beat-note heterodyne mode. These results are directly correlated with the Fermi surface reconstruction induced by phase transitions. This work positions geometrically frustrated lattices as a powerful platform for studying correlated quantum phenomena, offering new pathways for the design of advanced quantum devices.
