Chemoselective Difluorination of Tetramic Acids in Water.
Article in ACS omega, 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
3,3-Difluorotetramic acids are key building blocks for the construction of medicinally relevant compounds. However, general methods for their synthesis via the direct electrophilic fluorination of tetramic acids are lacking. Herein we report such a method for the direct 3,3-difluorination of tetramic acids in water without any organic cosolvents utilizing Selectfluor as the electrophilic fluorine source. This reaction shows high chemoselectivity across a range of functional groups, including alkenes, alkynes, ketones, and aromatic rings, and tolerates a range of common nitrogen protecting groups. Finally, the reaction was successfully run at the multimillimole scale and was shown to tolerate an air atmosphere.
