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

Metal-insulator transitions in low band-gap systems emerge from the interplay of interactions, disorder, and band structure on comparable energy scales. Platinum diselenide, with its thickness-dependent electronic structure, provides an ideal platform to explore this regime, as the five-layer limit lies close to the semimetallic boundary while retaining a small bandgap (~0.1 eV). Here we show that hexagonal boron nitride-encapsulated five-layer PtSe
