Hepatitis B Virus Infection Among Tribal Populations in India: A Systematic Review and Meta-Analysis.
Synthesis in Public health reviews, 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
Objectives: The introduction of the Hepatitis B virus (HBV) vaccine has significantly reduced the disease's burden. Tribes comprise approximately 8.6% of the Indian population, making it pertinent to investigate the epidemiology of HBV among these individuals. We synthesized the prevalence of HBV among tribes in India. Methods: We searched the Medline (via the PubMed search engine), Embase, and CINAHL databases, in addition to the first 10 pages of Google Scholar. We included original observational studies that screened tribal populations for HBV infection, reported the prevalence of HBsAg (our main preference), and/or other markers. The risk of bias was assessed using the Appraisal Tool for Cross-Sectional Studies. The pooled prevalence was presented after conducting a meta-analysis (PROSPERO registration ID: CRD42022334938). Results: A total of 24 studies were selected for this study. The pooled prevalence of HBV (as measured by the proportion of individuals testing positive for hepatitis B surface antigen) was estimated to be 9.99% (95% confidence interval (CI) 6.07-14.75, I Conclusion: A considerable prevalence of HBV was observed in tribal communities in India, a fact that cannot be overlooked. This information may be useful for planning HBV vaccination strategies among tribes in India.
