Gut Microbiota Disorders in Obesity-Associated Benign Prostatic Hyperplasia in Rats.
Article in Biochemical genetics, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
Benign prostatic hyperplasia (BPH), commonly seen in older men, can cause symptoms of discomfort, and may even need surgical intervention. Studies have shown the potential link between gut microbes and BPH, but the molecular association is not fully understood.
methodsFour-week-old male Sprague-Dawley rats (n = 16) were randomly allocated to normal control diet (ND, 10% fat) and high-fat diet-induced BPH (HFD, 45% fat) groups. Metagenomic analysis was used to examine the abundance and discrepancies in gut microbiota within the two groups after 24 weeks of feeding. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis was conducted to assess the biological functions of the differentially expressed genes.
resultsRats with HFD-induced obesity exhibited morphological abnormalities in their prostate tissues. Metagenomic analysis of the gut revealed that Firmicutes were the dominant phyla in the HFD group, whereas the ND group had a higher abundance of Spirochaetes. At the genus level, Ruminococcus spp exhibited greater abundance in the HFD group, whereas Treponema spp were more abundant in the ND group. KEGG analysis demonstrated that the differentially expressed genes were mainly enriched in the NOD-like receptor (NLR) signaling, PI3K-Akt signaling, estrogen-signaling, signalings associated with GABAergic synapses, pantothenate and CoA biosynthesis.
conclusionThe findings of our study indicated that there was a notable variation in the microbiota abundance within the intestinal tract of obese rats suffering from prostate hyperplasia. It is plausible that these differentially abundant bacteria played a role in the development of pathological alterations in the prostate through the facilitation of inflammatory responses; however, additional research is required to validate the findings.
