Enhanced Oral Delivery of Turmeric Extract via Spray-Dried Microparticles: Biopharmaceutical Performance and In Vitro Microbiota Modulation.
Article in International journal of molecular sciences, 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
To overcome the bioavailability limitations of turmeric, this study developed a spray-dried turmeric extract microparticle (TEM) formulation for improved oral delivery. We investigated its transport, anti-cancer properties, anti-inflammatory effects, and impact on gut microbiota. The TEM formulation successfully improved curcuminoid dissolution by approximately 40-fold and 5-fold compared with unencapsulated extract and curcumin, respectively, and demonstrated effective transepithelial transport. Notably, the TEM formulation showed twofold superior inhibition of gastric cancer cell growth compared to curcumin and significantly suppressed nitric oxide production compared to unencapsulated extract. Furthermore, fecal fermentation studies confirmed that TEMs modulate gut microbiota, with acetate as the predominant metabolite. These findings suggest that TEMs represent a promising standardized approach for managing gastrointestinal diseases.
