1 · What the graph read from 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.

2 · The registry

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

backgroundBenign prostatic hyperplasia (BPH) is a common urological condition affecting middle-aged and elderly men, and it significantly impairs their quality of life. Although metabolic disorders are suspected to contribute to BPH, the causal relationship between metabolic markers and BPH remains unclear due to the limitations of traditional observational studies.

methodsIn this study, Mendelian randomization (MR) analysis was performed by integrating genome-wide association study (GWAS) data from European populations, integrating metabolites from the GWAS Catalog, BPH-related GWAS data from OpenGWAS, and gene expression data from GEO. Five regression models were used for two-sample MR analysis, with reverse MR analysis also performed. Sensitivity analyses were carried out through stringent instrumental variable selection criteria, including heterogeneity tests, horizontal pleiotropy tests, and leave-one-out analysis. Additionally, differential gene expression analysis, consensus clustering of BPH subtypes, characteristic gene screening, diagnostic model construction, immune infiltration analysis, and single-gene Gene Set Enrichment Analysis (GSEA) were performed.

resultsMR analysis identified several metabolic markers, including total cholesterol, valine, and alanine in HDL, that were significantly associated with BPH, all acting as risk factors. Reverse MR analysis revealed no evidence of reverse causal effects of BPH on most metabolic markers. Additionally, distinct BPH subtypes were identified, along with three key genes (GRAMD2B, HEBP2, and STRADB). A highly accurate diagnostic model was constructed based on these genes.

conclusionThis study elucidates the causal relationship between metabolic markers and BPH, offering new insights into the etiology, diagnosis, and treatment of the disease. However, limitations include the lack of in vitro experimental validation. Future research should address these limitations, further explore the pathogenesis of BPH, and facilitate the development of more effective prevention and treatment strategies.
