Generation of a 3-Allyl/Propanylthiomethyl Ketene and their [4+2] Cycloadditions With 1,3-Diazabuta-1,3-dienes: Synthesis of 5-Allyl/propargyl-thio methyl Pyrimidinones.
Article in Chemistry & biodiversity, 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
The manuscript describes the explorations on [4+2] cycloaddition of newly in situ generated 3-(allyl/propargyl-thio)propanone as 2π-components with functionalized 1,3-diazabuta-1,3-dienes as 4π-components for the synthesis of 5-allyl/propargyl-thio methyl pyrimidinones. The synthetic methodology is simple to operate, mild, and successful with a wide range of functionalized 1,3-diazabuta-1,3-dienes in the development of functionalized pyrimidinones. The synthesis of these functionalized pyrimidinones is significant as functionalized pyrimidinones have diverse pharmacological relevance and are useful synthons for the synthesis of condensed heterocycles.
