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

Metallabenzenes are recognized as a unique class of aromatic compounds, not only of structural and theoretical interest but also as platforms to design powerful transformations. Here, we report the successful transmutation of a metallabenzene for pyridine synthesis. This 'metal-to-nitrogen swapping' process utilizes readily available ruthenabenzene phosphonium salts and commercially available 2-aminopyridines under mild conditions. The isolation of ruthena-azepines, containing a planar seven-membered aza-metallacycle, along with DFT calculations, supports the nitrogen insertion/metal deletion cascade driven by aromatization. Additionally, we investigate the tunable photophysical properties of the resulting pyridine phosphonium salts.
