Hepatitis Delta Virus Testing, Prevalence, and Liver-Related Outcomes Among US Veterans With Chronic Hepatitis B.
Article in Gastro hep advances, 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
Background and Aims: Hepatitis delta virus (HDV) infection in patients with chronic hepatitis B (CHB) is associated with worse liver-related outcomes. We aim to comprehensively evaluate HDV testing, diagnosis, and liver-related outcomes among a national cohort of US Veterans with CHB. Methods: US Veterans with CHB from 2010 to 2023 were evaluated to determine trends in HDV testing (anti-HDV antibody, HDV RNA) and proportion positive among those tested. HDV positive patients were 1:2 propensity score matched to CHB patients who were HDV negative to evaluate incidence (per 100,000 person-years) of cirrhosis, hepatic decompensation, or hepatocellular carcinoma using competing risks Nelson-Aalen methods for estimating cumulative hazards. Results: Among the 27,548 CHB patients identified, 16.1% completed HDV testing, among whom 3.25% (n = 144) were positive. After excluding patients with cirrhosis or HCC at baseline, 71 patients with HDV (median follow-up 5.3 years, interquartile range 2.5-7.6) were propensity score matched to 140 CHB patients without HDV (median follow-up 4.5 years, interquartile range 2.6-8.1). Compared to CHB patients without HDV, those with concurrent HDV had significantly greater incidence of cirrhosis (4.39 vs 1.30 per 100,000 person-years, Conclusion: Among a national cohort of US Veterans with CHB, low rates of HDV testing were observed. This is concerning given that patients with concurrent HDV infection had >3 times and >5 times greater risks of cirrhosis and hepatic decompensation, respectively, compared to CHB patients without HDV, highlighting the importance of timely HDV diagnosis and treatment.
