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

Pyridylphosphonium salts, which are readily available and air and thermally stable, have been used to effectively synthesize structurally diverse pyridines. Herein, we report the pnictogen bonding (PnB) enabled photoactivation of pyridylphosphonium salts with catalytic potassium carbonate to generate pyridyl radical for pyridine synthesis. Remarkably, this light-driven transformation allowed chiral pool synthesis with excellent chirality retention, giving a wide range of chiral selenium-containing pyridines. On the basis of our combined computational and experimental studies, we propose that the PnB between pyridylphosphonium salts and potassium carbonate enables access to the photoactive charge transfer complex, which is able to undergo single electron transfer to generate pyridyl radical for its transformation.
