Synthesis of Functional Water-Soluble Polyesters Based on Citric Acid and Dimethylolpropionic Acid.
Article in ACS polymers Au, 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
Aiming for renewable polymers with potential recyclability and biodegradability, polyesters are very promising due to an increasing number of available biobased monomers and ester bonds that can be hydrolyzed under specific conditions. Citric acid, for example, is a biobased, nontoxic, cheap, and easily available resource. Its multifunctionality enables the synthesis of polyesters with free carboxy groups, thus providing possibilities for further functionalization and cross-linking. Citric acid and dimethylolpropionic acid were used to synthesize water-soluble polyesters via melt polycondensation at 150 °C without the need for potentially hazardous catalysts. The resulting polyesters displayed a significant amount of free carboxylic acid groups (8 mmol g
