Superior solubility of anhydrous quercetin and polymer physical mixtures compared to amorphous solid dispersions.
Article in RSC advances, 2025. 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
Quercetin (QUE) is a functional flavonoid molecule with low water solubility. The study of its amorphous solid dispersions (ASDs) is still insufficient. This work reveals that the solubility of the physical mixtures of anhydrous QUE and polymers (PVP or soluplus) is better than that of the ASDs of QUE and the corresponding polymers. Gel-like phase separation occurring during the QUE ASDs dissolution process (weak in ASDs with PVP and strong in ASDs with soluplus) reduces the driving force for QUE release, which makes research on the QUE ASDs insufficient, and can be avoided in the QUE physical mixtures with polymers. Combination of metastable polymorph and polymer is a feasible strategy for improving the solubility of poorly water-soluble molecules whose ASDs encounter the gel-like phase separation.
