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 development of highly selective gas sensors operating at room temperature with detection capabilities in the parts-per-billion (ppb) range is one of fundamental and technological interest across diverse fields. Conventional sensor arrays often suffer from signal instability, large device footprints, and high fabrication costs. The emergence of two-dimensional (2D) materials has enabled new paradigms in chemiresistive sensing, leveraging their quantum confinement, high surface-to-volume ratio, and tunable electronic structure. In this study, we present, for the first time, a high-performance chemiresistive sensor based on chemically exfoliated γ-graphyne, a carbon allotrope with sp-sp
