Association between periodontitis and hepatocellular carcinoma across different tumor stages.
Article in BMC oral health, 2026. 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
objectivesHepatocellular carcinoma (HCC) is a malignant liver cancer. While periodontitis associates with many chronic liver diseases, oral health data of HCC patients remain limited. This study assessed dental/periodontal health differences across different stages and confirmed the association between periodontitis and HCC. MATERIALS AND
methods113 HCC patients and 30 healthy volunteers were enrolled. HCC patients were stratified by China Liver Cancer Staging (CNLC): Ⅰa, Ⅰb, Ⅱa, Ⅱb, Ⅲa, and Ⅲb. Biochemical tests and oral examinations data were collected at HCC patients’ admission and analyzed to their oral characteristics and explore correlations between periodontitis and various liver-related indicators.
resultsCompared with healthy individuals, HCC patients exhibited significantly increased periodontal probing depth (PD), gingival recession, clinical attachment loss (CAL), bleeding on probing (BOP), and higher tongue disease prevalence. Additionally, stage Ⅲb patients had the most severe periodontitis. Logistic regression identified PD, tooth loss, and BOP as HCC-associated factors. Correlation analysis showed that PD was significantly correlated with aspartate transaminase, alanine transaminase, fibrinogen, D-dimer, alpha-fetoprotein, and protein induced by vitamin K absence or antagonist-II. BOP was significantly correlated with aspartate transaminase, alkaline phosphatase, γ-glutamyl transpeptidase, activated partial thromboplastin time, and D-dimer (all P < 0.05).
conclusionsPeriodontitis is associated with HCC. PD and BOP correlate with key HCC markers. These findings emphasize the relationship between periodontitis and HCC and highlights the need for interdisciplinary collaboration between dentistry and hepatology to optimize oral care and overall management of HCC patients.
