[Pentosan polysulfate alleviates cyclophosphamide-induced interstitial cystitis/bladder pain syndrome in mice by modulating gut microbiota and bile acid metabolism].
Article in Nan fang yi ke da xue xue bao = Journal of Southern Medical University, 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
objectivesTo investigate the therapeutic efficacy and mechanism of pentosan polysulfate (PPS) for cyclophosphamide (CYP)-induced interstitial cystitis/bladder pain syndrome (IC/BPS) in mice.
methodsFemale C57BL/6 mice (6-8 weeks old) were randomized into control group, PPS treatment (25 mg/kg via gavage for 3 weeks) group, CYP treatment (3 separate intraperitoneal injections at 50 mg/kg in week 4), and CYP+PPS treatment group. Gut microbiota alterations of the mice were analyzed using 16S rDNA sequencing and non-targeted metabolomics. Fecal microbiota transplantation (FMT) was performed in CYP-treated recipient mice and those treated with both CYP and PPS. In the
resultsPPS treatment significantly improved the mechanical pain thresholds, restored the urodynamic parameters, and attenuated bladder inflammation and barrier dysfunction in CYP-treated mice. Mechanistically, PPS enriched the abundance of
conclusionsPPS ameliorates IC/BPS in mice by remodeling gut microbiota to enhance DCA production and activate TGR5 signaling, suggesting a novel microbiota-bile acid-TGR5 axis that mediates the therapeutic effect of PPS and a therapeutic strategy for IC/BPS by targeting gut-bladder crosstalk.
