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.
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
A mild catalytic strategy for sulfur-retentive C-S bond cleavage of simple sulfides has been developed through cooperative zirconocene and photoredox catalysis. In contrast to conventional desulfurization and radical-generation strategies, which were primarily designed to exploit the carbon fragment upon C-S bond cleavage, this method converts structurally simple sulfides into carbon-centered radicals and isolable or synthetically usable thiols under mild conditions. The transformation is driven by the formation of a strong Zr-S bond and accommodates a broad range of substrates, including benzyl and allyl sulfides, thioglycolates, thioacetals, and cysteine derivatives. The carbon-centered radicals participate in hydrogenation and intermolecular alkylation reactions, while the thiol fragments are conserved as versatile synthetic handles for subsequent functionalization. This strategy establishes simple sulfides as bifunctional precursors that enable productive utilization of both fragments generated upon C-S bond cleavage.
