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

Owing to the lack of precise atomic-level control offered by existing fabrication techniques over the edge structures in bilayer graphene, experimental studies on the edge effects in bilayer graphene structures have so far largely remained unexplored. In this study, two fully cove-edged bilayer nanographenes (CBGs) are synthesized via organic synthesis approach. One of the prepared CBGs contains a cavity defect. The bilayer stacked structures of CBGs are unambiguously characterized. Two CBGs exhibit a parallel displaced stacking arrangement with tunable interlayer overlapping, which is controlled by the steric hindrance at the cove edges. The different interlayer overlapping results in different interlayer electronic coupling. The decrease in the energy gaps is linked to the cove edges, which leads to a redshift in the optical absorption and emission spectra of the CBGs, which is further used for the NIR-II bioimaging.
