Bioinformatic strategies in metagenomics of chronic prostatitis.
Article in World journal of urology, 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
purposeChronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a prevalent urological condition in young men, significantly affecting quality of life due to persistent discomfort and neuropsychological symptoms. Despite its high prevalence, the etiology of CP/CPPS remains poorly understood. This study investigated urinary microbiota differences between CP/CPPS patients and healthy controls to identify microbial contributors, antibiotic resistance genes (ARGs), and virulence factors of dominant bacteria, as well as to explore potential therapeutic targets.
methodsUrine samples were collected from 58 CP/CPPS patients and 25 controls. Symptom severity was assessed by a specialist urologist using the NIH Chronic Prostatitis Symptom Index and UPOINT classification. Bacterial-specific 16 S rRNA sequencing was performed using nanopore technology, with bioinformatics analyses conducted via ONT guppy 5.0.11, NCBI and SLV 16 S bacterial taxonomic databases, UPGMA hierarchical clustering, and the Bacterial and Viral Bioinformatics Resource Center (BV-BRC). Pairwise comparisons were analyzed using the Mann-Whitney U test.
resultsDistinct microbial diversity patterns were observed between patients and controls. Bacillus species were significantly enriched in CP/CPPS patients, while Enterococcus species predominated in controls. Younger patients exhibited unique microbiome profiles compared to older groups. Bioinformatics analyses identified ARGs and virulence factors associated with Bacillus species, implicating them in localized inflammation. Antibiotics like pleuromutilin or vancomycin were identified as potential therapeutic options, though experimental validation was beyond the study's scope.
conclusionThese findings highlight microbial imbalances and provide a foundation for microbiome-targeted therapeutic strategies for CP/CPPS management in the future. Additionally, the identification of bacterial virulence factors and ARG provides insights into the potential mechanisms driving persistent symptoms. Future research with larger cohorts and experimental validation of the suggested therapeutic options may contribute to more effective treatment for CP/CPPS.
