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
Ulcerative colitis (UC) remains a clinical challenge due to limited efficacy and side effects of conventional therapies, highlighting the need for novel interventions. Here, we investigate the therapeutic potential of naturally derived self-assembled nanoparticles (XDNPs) from the traditional Chinese medicine formula Xiexin Decoction (XXD) and rationally designed carrier-free nanoparticles (RBNPs) composed of berberine (BBR) and rhein. Both formulations effectively mitigated DSS-induced colitis by normalizing gut dysbiosis, reducing the release of pro-inflammatory mediators and facilitating macrophage phenotypic switching. Mechanistically, activity-based protein profiling identified VDAC1 as a direct functional target of BBR. Binding to VDAC1 inhibits its oligomerization, preventing the cytosolic release of oxidized mitochondrial DNA and subsequent activation of the NLRP3 inflammasome in macrophages. Co-assembly with rhein further enhances cellular uptake and bioavailability, amplifying anti-inflammatory efficacy. Proteomic and molecular analyses confirmed broad modulation of immune and metabolic pathways, while
