High hepatitis B vaccination coverage among a cohort of predominantly men who have sex with men in Germany.
Observational study in Human vaccines & immunotherapeutics, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Incidence of hepatitis B virus (HBV) infection has declined dramatically since the introduction of the HBV vaccine, but gaps remain in coverage. We characterized factors associated with vaccination among individuals with sexual risk of HBV infection. The BRAHMS observational cohort enrolled men and transgender women, without HIV, aged 18-55 years, with behavioral vulnerability to sexually transmitted infections at 10 German outpatient clinics. HBV surface antigen, surface antibody, and core antibody were assessed at screening for cohort eligibility to determine HBV vaccination status. Modified Poisson regression with robust standard errors was used to calculate adjusted prevalence ratios (aPR) and 95% confidence intervals (95% CI) for factors potentially associated with prior HBV vaccination. A total of 1,042 participants were included in these cross-sectional analyses, with 831 participants (79.7%) immune to HBV due to vaccination. Knowledge around HBV vaccination recommendations (aPR: 0.87; 95% CI: 0.78-0.98). and age (aPR 40-49 vs 18-29 years: 0.88; 95% CI: 0.79-0.97) were significantly associated with a history of HBV vaccination in both the unadjusted and adjusted models. Education about the availability of vaccines and recommendations for vaccinations may improve coverage.
