Long-Term Persistence of Hepatitis A Virus Immunity in Healthcare Workers Upto 25 Years After Vaccination.
Article in Journal of viral hepatitis, 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 A virus (HAV) remains globally endemic, particularly in populations with limited sanitation and poses risks to travellers and healthcare personnel. Although vaccination provides long-term protection, data on the duration of immunity in occupationally exposed groups are limited. We conducted a prospective cohort study among healthcare personnel and medical students vaccinated with either a monovalent HAV vaccine (Havrix, Avaxim) or a combined HAV/HBV vaccine (Twinrix) between 1996 and 2003 at Bari University Hospital, Italy. Vaccination records were verified, and serum anti-HAV IgG concentrations were quantified using CMIA (ARCHITECT HAVAb-IgG). Statistical analyses included Student's t-test, χ
