Prevalence of hepatitis B in Latin America and the Caribbean: a systematic review and meta-analysis.
Synthesis in Archives of virology, 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
Hepatitis B is a health threat with regional variations in prevalence. Our aim was to conduct a systematic review and meta-analysis of available data on the prevalence of hepatitis B virus (HBV) in Latin America and the Caribbean (LAC). A literature search was conducted from 2000 to 2024 using the databases Medline, Embase, LILACS and Web of Science, following PRISMA guideline. Search terms included: “hepatitis B virus”, “HBsAg”, “HBV”, “prevalence”, and “Latin America and the Caribbean”. Random-effects meta-analysis was performed to estimate the prevalence of HBV (HBsAg), and the I2 statistic was used to assess heterogeneity between studies. Subgroup and meta-regression analyses were performed to investigate possible sources of heterogeneity. In total, 190 studies were included in the analysis and the estimated global prevalence of HBV was 1.0% (95% CI: 1.0%-1.0%). In population subgroup analyses, the prevalence in general population was 1.0%, indigenous people was 6.0%, HIV-infected individuals was 5.0%, and inmates was 1.0%. The prevalence found was 2.0% in the period of 2000–2008, 1.0% in 2009–2016, and 1.0% in 2017–2024. The prevalence trends over time in the general population, indigenous people, HIV-infected individuals and inmate subgroups were 1.0%, 11.0%, 6.0% and 12.0% in the period of 2000–2008, 1.0%, 4.0%, 3.0% and 0.0% in 2009–2016, and 1.0%, 5.0%, 8.0% and 0.1% in 2017–2024, respectively. In LAC, HBV prevalence decreases over time, but risk subgroups stand out with elevated prevalence, such as indigenous people and HIV-infected individuals. Strategies to expand testing, treatment and vaccination with a focus on these subgroups may be relevant to reduce the prevalence of HBV.
