Prevalence of hepatitis B virus infection and treatment eligibility in Lesotho, Southern Africa: a population-based cross-sectional study with case-based follow-up.
Article in BMJ public health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background and aims: There is no data on hepatitis B virus (HBV) prevalence and treatment eligibility among the general population in Lesotho. We aimed to determine the prevalence of HBV infection in a large-scale cross-sectional survey among the general population in Lesotho, assess determinants of seropositivity, and evaluate treatment eligibility according to the 2024 WHO guidelines. Approach and results: We conducted a household-based, cross-sectional survey among participants≥10 years old in 120 randomly sampled village clusters in two districts. From participants screened positive for HBV surface antigen (HBsAg), we collected dried blood spots for HBV DNA measurement and referred the participants to health facilities for clinical assessment and treatment eligibility evaluation.Out of 6709 participants screened, 6705 had a valid HBsAg test result (3509 (52.3%) female, median age 33 years (IQR: 20-53)), which was positive in 78 participants, yielding a prevalence of 1.2% (95% CI: 0.9 to 1.4). Being≥18 years old, male, living in urban areas, living with HIV, consuming tobacco and belonging to higher wealth index quintiles, were associated with increasing odds of HBV infection. Of the 78 participants with HBV infection, 62 (79.5%) linked to care. Among these, 25/62 (40.3%) were also living with HIV and 23/25 (92%) already taking antiretroviral treatment active against HBV. Among the remaining, 10/37 (27.0%) were eligible for antiviral treatment based on HBV DNA, Aspartate aminotransferase to Platelet Ratio Index or alanine aminotransferase levels. Conclusions: We observed a low prevalence of HBV infection among Basotho. Treatment eligibility was high mostly due to the presence of HIV co-infection. However, nearly one-third of HBV mono-infected participants were eligible for treatment, suggesting a testing and treatment gap in this population.
