Generation of Donor/Donor Copper Carbenes through Copper-Catalyzed Cycloisomerization/Oxidation of Vinyl-Allenes: Constructing Functionalized Cyclopentenones.
Article in Chemistry, an Asian journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Transition-metal-catalyzed cycloisomerization of vinyl-allenes has attracted enormous attention over the past decades, and multitudinous efficient synthetic strategies have been discovered based on this methodology. However, the generation of metal carbenes in these reactions is mostly limited to the noble-metal catalysts (Au and Pt). Here we show that non-noble-metal catalyst (Cu) enable the catalytic cycloisomerization/oxidation of vinyl-allenes by generating α-alkyl alkenylcopper carbenes. This protocol leads to the practical and controllable construction of various valuable cyclopentenones in mostly good to excellent yields.
