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

Heteroatom doping into graphene has attracted wide attention for tailoring electronic, physical, and chemical properties of graphene. In order to achieve the application of doped graphene in an effective manner, it is essential to use films with a large area and a precise number of layers. Therefore, it is necessary to develop a technique for heteroatom doping directly into CVD-grown large-area graphene. In this study, high-energy heavy ion irradiation to the heterostructure of the KCl layer and the CVD-grown single-layer graphene film allowed the formation of Cl-C chemical bonds. The spectroscopic analysis indicated that the doping of graphene by Cl atoms, at a concentration of 10.2 atom %, had occurred as a result of the irradiation of 3.0 MeV Ni
