Incidence of Chronic Hepatitis B Virus Infection Among People With HIV in Yunnan Province, China: A Retrospective Observational Cohort Study (2004-2024).
Article in Open forum infectious diseases, 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
Background: Hepatitis B virus (HBV) exacerbates mortality and morbidity in individuals with human immunodeficiency virus (HIV), but limited research has been conducted on incidence of HBV in people with HIV (PWH). Methods: We herein conducted a retrospective cohort study of PWH in Yunnan province, China. PWH who underwent antiretroviral therapy (ART) and whose status was initially negative for hepatitis B surface antigen (HBsAg) were enrolled and followed-up with from 2004 to 2024 to analyze chronic HBV infection incidence and associated factors. Results: A total of 40 086 HBsAg-negative PWH underwent at least 1 follow-up test, contributing to a cumulative observation time of 221 049.8 person-years (PYs). Of the included individuals, 894 chronic HBV infections were identified, corresponding to a HBsAg-emia incidence of 2.23%, resulting in an overall incidence rate of 0.40 per 100 PYs (95% CI: 0.38-0.43). We ascertained that individuals who acquired their infection as an injectable drug user (adjusted hazard ratio [aHR, 1.50]) and who exhibited low ART adherence (aHR, 1.46) were primarily associated with a higher incidence of chronic HBV infection. Those individuals who were enrolled post-2014 (aHR, 0.81) were linked to a lower incidence of HBV, indicating a 19% relative reduction in chronic HBV infection compared to those enrolled pre-2014. Conclusions: The reduction may have been linked to factors such as introduction of hepatitis B vaccination, a decrease in proportion of HIV infections transmitted through injectable drugs, and improved effectiveness of ART. We posit that our efforts should focus in the future on enhancing immunization, treatment, and behavior intervention in this population.
