Association of IL-1β Gene Polymorphism with Prostate Cancer Severity, Prostate Volume, and PSA Levels: A Case-Control Study.
Article in Asian Pacific journal of cancer prevention : APJCP, 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
backgroundProstate cancer (PCa) is the second leading cause of death from cancer among men. The development of prostate cancer depends on chronic inflammation and cytokines, including interleukin-1 beta (IL-1β). The objective of the research was to test the association between SNP (rs16944) in interleukin-1 β (IL-1β) gene and serum levels of Prostate Specific Antigen (PSA) and testosterone concentrations in patients with prostate cancer.
methodsThis was a case-control study on 40 prostate cancer patients and 40 controls at Kirkuk City. The levels of serum prostate-specific antigen (PSA), prostatic acid phosphatase (PAP), testosterone, and prostate volume were determined by enzyme-linked immunosorbent assay. The ARMS-PCR was used to genotype the IL-1β , which was followed by statistical analysis of the association of genotypes with Gleason and clinical parameters with the help of Student's t-test, chi-square test, and correlation. The general significance level of the p-value is less than 0.05.
resultsSignificant differences were observed in PSA levels (36.4 ± 2.17 ng/ml in PCa vs. 0.91 ± 0.09 ng/ml in controls; P = 0.001), PAP levels (3.54 ± 1.51 IU/L vs. 0.87 ± 0.28 IU/L; P = 0.001), testosterone (6.54 ± 0.87 ng/ml vs. 3.27 ± 1.98 ng/ml; P = 0.011), and prostate volume (79.17 ± 6.26 cm³ vs. 23.21 ± 2.17 cm³; P = 0.001). IL-1β genotyping showed that the genotype AG and AA were more frequent among PCa patients than among the controls. The AA genotype was highly correlated with better Gleason scores (P = 0.021), increased prostate volume (P = 0.041), and increased levels of PSA (P = 0.034).
conclusionIIL-1β polymorphism, particularly the AA genotype, is associated with increased PSA levels, larger prostate volume, and more aggressive prostate cancer phenotypes. These findings underscore the potential of IL-1β genotyping as a biomarker for prostate cancer severity and progression.
