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
Introduction: Ulcerative colitis (UC) is a chronic intestinal disease characterized by spleen-lung qi deficiency and dampness-pathogenic obstruction. Although there are various treatment options available, patients frequently encounter significant drug-related side effects. Previous studies have shown the potential of Methods and Results: We synthesized a negatively charged amphipathic prodrug called CPA-SA-DHA (CSD), which consists of CPA as the hydrophilic component, and succinic anhydride and docosahexaenoic acid as the hydrophobic segments. The CSD nanoparticles obtained had a particle size of 180.0 ± 3.2 nm, a negative zeta potential of -29.8 ± 5.3 mV, and a uniform shape with a PDI index of 0.230 ± 0.003. The interaction between positive and negative charges significantly increased the retention time of CSD nanoparticles in the colonic microenvironment. Furthermore, CSD nanoparticles demonstrated enhanced bioavailability in UC mice compared to CPA. Additionally, we observed that CSD nanoparticles exhibited therapeutic effects on DSS-induced UC mice by regulating the diversity and abundance of gut microbiota. This effect may be mediated by the inhibition of pro-inflammatory signaling pathways TLR4/NF-κB. Conclusion: These findings confirm the potential of CSD nanoparticles as a promising treatment option for UC.
