Association between hepatitis B and C viruses and head and neck lymphoma: A case-control study.
Article in Brazilian journal of otorhinolaryngology. 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
objectiveThis study aims to assess the relationship between Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) infections and Head and Neck (H&N) lymphoma in a region where HBV and HCV are highly prevalent.
methodsPatients diagnosed with H&N lymphoma between 2013 and 2022 at our institution were eligible for the study, with exclusion criteria applied to patients with a history of recurrence, other cancers, HIV infections, organ transplantation, and those below 18-years of age. The first and the second control group comprised outpatients and patients diagnosed with Head and Neck Squamous Cell Carcinoma (HNSCC) who were gender and age-matched at the same hospital. Logistic regression analysis, which was adjusted for sex, age, smoking, alcohol consumption, Rheumatoid Arthritis (RA), and Systemic Lupus Erythematosus (SLE), was utilized to estimate the Odds Ratio (OR) and 95% Confidence Interval (95% CI) for HBV and HCV infection status.
resultsFrom 2013 to 2022, 304 patients with H&N lymphoma were identified. After excluding those with a history of other cancers or recurrences, 262 patients remained. The first control group included 1048 matched outpatients. Additionally, 262 patients diagnosed with HNSCC during the same period were selected as the second control group. Of the 242 Non-Hodgkin Lymphoma (NHL) patients, 102 had Extranodal Lymphoma (ENL). Of these ENL patients, 49 tested positive for HBV and 17 for HCV. After controlling for the confounding factors, NHL patients with HBsAg positivity had a significantly higher prevalence rate than healthy controls, particularly among B-cell Lymphoma and Diffuse Large B-Cell Lymphoma (DLBCL) patients. Furthermore, there were no significant differences in HCV infections between the three groups.
conclusionsIn conclusion, the study found a significant link between HBV infection and H&N NHL, particularly DLBCL in Taiwan. However, no significant link was discovered between HCV infection and H&N lymphoma. These findings suggest a potential role for HBV in the development of H&N NHL and DLBCL. LEVEL OF EVIDENCE: 4:
