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

The reversible σ-dimerization of radicals is a fundamental process in bond formation and cleavage, yet achieving this with an isolable heavy carbyne analogue has remained a paramount challenge. Herein, we report the synthesis and characterization of an isolable germylyne radical that demonstrates remarkable ambient stability while undergoing clean, reversible σ-dimerization via a Ge-Ge single bond. This reversible process, which exhibits a pronounced thermochromic response, is thoroughly elucidated through variable-temperature NMR/EPR spectroscopy and X-ray crystallography, revealing a moderate bond dissociation enthalpy. Beyond dimerization, this germylyne radical acts as a versatile synthon for main-group bond activation, readily cleaving chalcogen-chalcogen (S-S, Se-Se), phosphorus-phosphorus (in P₄), and even challenging aromatic carbon-chlorine (C-Cl) bonds. This work provides the direct structural evidence of a heavy carbyne's dimerization pathway and establishes a new platform for dynamic covalent bonding in main-group chemistry, with implications for stimuli-responsive materials and radical-mediated activation.
