Retrospective cohort study of hepatitis B immunization strategy effects in Beijing across 30 years.
Article in Nature communications, 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
Whether a booster dose of hepatitis B vaccine is necessary for adolescents remains controversial. We conducted a retrospective cohort study from the Immunization Information System and The National Notifiable Disease Reporting System to evaluate the impact of hepatitis B virus (HBV) vaccination programs (universal infant hepatitis B immunization and adolescent booster) on HBV infection. The vaccine effectiveness (VE) of hepatitis B vaccine is 64.43% (95% CI 57.78% - 71.08%) within 10 years of birth, escalates to 95.36% (95% CI 94.84% - 95.88%) by 20 years, and decreases to 67.35% (95% CI 63.86% - 70.85%) by 30 years. Compared with Beijing's birth-vaccinated-only group, the booster group showed a lower relative VE in the first 10 years but a slight increase thereafter. Compared with the national control group, the booster group maintained a relatively high relative VE with a smaller decline magnitude. This study demonstrates that adolescent HBV booster vaccination administered during junior high school improves hepatitis B surface antibody levels and contributes to a further reduction in the incidence of HBV infection.
