Synthesis of Chiral Spiro-2-pyrrolidinones with Anti-Inflammatory Properties.
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
Spiro motifs are privileged three-dimensional scaffolds that offer a balance of rigidity and flexibility. Herein, we report the synthesis of spiro-2-pyrrolidinones via a Michael addition reaction promoted by bifunctional organocatalysts, involving cyclic 1,3-ketoesters and nitroalkenes to generate products bearing two stereocenters. Through a sequence involving ketone reduction, nitro-group reduction followed by lactamization in a one-pot procedure, and finally oxidation, requiring a single chromatographic purification, we obtained 18 chiral spiro-2-pyrrolidinones with different substituents in the lactam ring and different rings spiro-fused to the 2-pyrrolidinone moiety. The resulting compounds were evaluated for
