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

Effusion measurements are performed to determine the hydrogen concentration and its binding energies in large area graphene. The samples were grown by chemical vapor deposition using deuterium and deuterated methane as readily identifiable isotopes that duplicate hydrogen chemistry. In a second step, graphene is transferred to silicon substrates covered with an oxide layer of different thickness. H binding energies and the H density-of-states distributions are derived from the effusion spectra. The data show a well defined peak in the H density-of-states at 1.97 eV that is influenced by the thickness of the oxide layer. This is discussed in terms of a model that describes the dissociation of C-H bonds.
