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

In this study, stable tetrazene radical cation salts were synthesized and characterized for the first time. The radical cation derived from 1,2-di(2-azaadamantan-2-yl)diazene (DAD) was isolated as an air-stable solid, retaining its integrity for at least 120 days at ambient temperature (∼25 °C) and pressure. X-ray crystallography and electron spin-resonance spectroscopy revealed the delocalization of the unpaired electron over the tetrazene core and into the adamantane framework. DAD undergoes two well-separated, reversible redox processes and displays high catalytic activity for alcohol oxidation under mild conditions. Systematic structural modifications identified the key framework features governing the radical cation stability and catalytic performance.
