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

Atomic hydrogen (H•), the union of an electron and a proton, is the smallest radical of the universe. Over the past century, advanced techniques such as electric discharge and mercury UV sensitization enabled a fundamental understanding of the reactivity of H• but fell short of providing synthetic methods to exploit its intriguing properties. Here we report a light-mediated method to access hydrogen radicals under synthetically useful conditions. This strategy enabled the mild, metal-free reduction of highly functionalized alkenes and halides. Mechanistic, EPR, and DFT studies suggest hydrogen radical generation via a Rydberg radical intermediate, with potential applications across the chemical and biological sciences.
