Hepatitis B Care and Treatment in Zanzibar, Tanzania: A Demonstration Project Following 2015 WHO Treatment Guidelines, 2017-2021.
Article in Journal of viral hepatitis, 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
Zanzibar, a low-resource semiautonomous region of Tanzania, has an estimated prevalence of hepatitis B virus (HBV) infections of 3.6%. To assess the feasibility of care and treatment, a 5-year hepatitis B demonstration project was implemented in Zanzibar during January 2017-December 2021, following the 2015 WHO HBV care and treatment guidelines. Participants included adults (aged ≥ 18 years) who tested positive for HBV surface antigen and tested negative for HIV and hepatitis C antibody. Participants were examined for clinical signs of liver disease and testing was conducted at baseline to assess treatment eligibility and every 6-12 months thereafter. Tenofovir disoproxil fumarate (TDF) was provided at no cost to treatment-eligible participants. Clinical and laboratory data were analysed to assess improvement in proximal disease outcomes. Among 596 participants enrolled, the median age was 32 years (IQR 26-39) and 365 (61%) were male. Of those enrolled, 268 (45%) returned for ≥ 1 follow-up visit, with a median of 511 days of follow-up. Overall, 58 patients initiated treatment: 15 met treatment criteria based on liver cirrhosis alone; 13 by APRI > 1.5; among those with HBV DNA results, six met criteria based on HBV DNA levels and ALT activity; 24 met ≥ 2 criteria. Significant decreases in ALT activities, APRI scores and HBV DNA levels were observed among those treated. This hepatitis B care and treatment programme was demonstrated to be feasible in a low-resource setting. Despite challenges, testing and linkage to care is critical to decrease the global burden of hepatitis B.
