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

backgroundGenetic susceptibility to prostate cancer (PCa) varies across populations, yet East Asian men remain underrepresented in genome-wide association studies (GWAS). This study aimed to identify genetic variants associated with PCa in a Taiwanese cohort and to explore their potential biological relevance using integrative annotation approaches.

methodsWe analyzed 961 PCa patients and 3792 age-matched controls from the Taiwan Biobank. Genotyping and imputation were performed using the Taiwan Biobank 2.0 array and the 1000 Genomes East Asian reference panel. Association testing was conducted using logistic regression adjusted for age and population structure. Gene-based analysis using Multi-marker Analysis of GenoMic Annotation (MAGMA), functional annotation using HaploReg, and prostate tissue cis-expression quantitative trait loci (cis-eQTL) and splicing QTL (sQTL) evaluation using the Genotype-Tissue Expression project (GTEx) were performed to explore functional relevance.

resultsWe identified 371 genome-wide significant variants and 47 independent risk loci, including established regions (8q24.21, ZNF365, NCOR2, and PRKCB) as well as loci not previously reported in major GWAS (CCDC36, RAB6B, TTLL3, and PARD3B). MAGMA analysis identified 80 PCa-associated genes, and pathway analysis highlighted sphingolipid metabolism and leukocyte transendothelial migration. Integrative annotation indicated that several variants are located in regulatory elements and are associated with prostate-specific eQTL and sQTL effects. Additional analyses showed that several variants were associated with clinical indicators of disease aggressiveness, and age-stratified sensitivity analyses demonstrated consistent associations across age groups. Sensitivity analyses using alternative modeling approaches yielded comparable results.

conclusionsThis study identifies both established and putatively novel genetic loci associated with PCa in a Taiwanese cohort and provides functional insights through integrative annotation. These findings contribute to understanding the genetic architecture of PCa in East Asian populations and highlight candidate loci that require independent validation in future studies.
