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
backgroundThe potential involvement of JC polyomavirus (JCPyV) in prostate cancer (PCa) remains a subject of debate, as existing in vitro studies have produced conflicting results. Understanding the viral oncogenic mechanisms underlying prostate cancer could offer valuable insights into its etiology. This study aimed to explore the association between JCPyV infection and prostate cancer by detecting the viral large T-antigen gene in prostate tissue specimens.
methodsA case-control study was conducted from February 2022 to March 2023, including 100 participants: 50 diagnosed with prostate cancer (cases) and 50 with benign prostatic hyperplasia (BPH) as controls. Formalin-fixed paraffin-embedded (FFPE) prostate tissue samples were collected from all participants. Nested polymerase chain reaction (PCR) was employed to detect JCPyV large T-antigen DNA using specific primers. Demographic and clinical data were obtained via a structured questionnaire. Statistical analysis was carried out using SPSS version 20, and associations between JCPyV presence and prostate cancer were analyzed using logistic regression.
resultsThe mean age of the prostate cancer group was 67.5 ± 10.9 years, compared to 70.9 ± 8.9 years in the control group. JCPyV large T-antigen DNA was detected in 29 out of 50 (58%) prostate cancer cases, compared to 19 out of 50 (38%) controls (P = 0.045; odds ratio = 1.45; 95% confidence interval: 1.011 to 5.019). Within the prostate cancer group, patients testing positive for the JCPyV T-antigen had a mean age of 73.3 ± 8.7 years, significantly higher than T-antigen-negative patients, whose mean age was 67.0 ± 8.3 years (P = 0.029).
conclusionThe prevalence of JCPyV large T-antigen gene was significantly higher in prostate cancer patients than in individuals with benign prostatic hyperplasia. These findings suggest that JCPyV infection may be linked to an increased risk of prostate cancer, reinforcing prior studies that imply a potential oncogenic role for the virus in prostate carcinogenesis. Further investigations are necessary to elucidate the molecular mechanisms driving this association and its potential clinical implications.
