Association between periodontal disease and prostatic disease: a systematic review and meta-analysis of observational studies.

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
objectiveCurrent research highlights periodontal disease as a systemic inflammatory condition that may influence extra-oral diseases such as prostatic diseases, which prompted us to explore the potential association. To evaluate whether periodontal disease is associated with an increased risk of prostatic disease, including prostate cancer, benign prostatic hyperplasia (BPH), and prostatitis.
methodsA systematic search of observational studies concerning the relationship between periodontal disease and prostatic disease was performed in online databases PubMed, Embase, Web of Science, Scopus, CENTRAL, CNKI, and WanFang. Searches were conducted from database inception to 31 July 2025. Pooled hazard ratio (HR) or odds ratio (OR) with 95% confidence intervals (CIs) were synthesized. Subgroup analysis was used to detect the origin of heterogeneity, sensitivity analysis was employed to evaluate the robustness of the results, and publication bias analyses were also performed. R software was used to perform statistical analyses.
resultsSixteen studies that met the preset criteria were included in this study. In the pooled analysis, periodontal disease was associated with increased risk of prostate cancer (HR = 1.23, 95%CI: 1.16-1.29, p < 0.001) or BPH (OR = 1.55, 95%CI: 1.41-1.70, p < 0.001). Sensitivity analysis confirmed the robustness of the results. No obvious publication bias was found in the meta-analysis. Only one cohort study reported that chronic periodontitis increases the risk of prostatitis (HR = 2.521, 95%CI: 1.685-4.005, p < 0.001). The effect of periodontal treatment on prostatic disease is still unclear.
conclusionsThe systematic review and meta-analysis identified an observational association between periodontal disease and increased risks of prostate cancer and BPH. Because all included studies were observational, these results indicate association rather than causation, and further prospective and mechanistic studies are required to clarify temporality and causality.
