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

Synthesizing radicals that have both long lifetimes and high chemical reactivity remains a long-term challenge. Here, persistent phenyl radicals are successfully synthesized on Ag(111) by protecting the carbon radical site by designing the precursor molecule with suitable steric hindrance. As carbon-carbon coupling is prohibited, such radicals remain intact for longer than 6 hours at room temperature on Ag(111). Taking advantage of the long lifetimes, the as-synthesized radicals are directly characterized in the real space at the single-chemical-bond scale by means of bond-resolving scanning tunneling microscopy imaging. Accompanied by the excellent stability, the radicals exhibit high chemical reactivities and facilitate the intermolecular radical transfer reactions at extreme low temperature. The preparation of persistent radicals not only favors the characterization of a surface-stabilized radical in the real space but also aids in illuminating the detailed reaction pathways of subsequent radical-assisted reactions directly.
