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 B virus (HBV) poses a major occupational risk to healthcare workers (HCWs), particularly in moderate-to-high‑prevalence settings such as Zambia. Despite the availability of a safe and effective vaccine, coverage among HCWs remains suboptimal. Among HCWs, volunteer HCWs face unique challenges, including financial barriers, that increase their risk. However, they are often overlooked in research. The present study aimed to determine HBV vaccination uptake and its predictors among volunteer HCWs in Zambia. Methods: This national cross-sectional study utilized a self-administered semi-structured online questionnaire to collect data from volunteer HCWs from October 3 to November 26 2024. Using R version 4.6.0 and Stata version 17, descriptive and inferential statistical analyses were performed. A two-sided Results: Among the 173 participants, 51 (29.5%) reported being vaccinated. Of the 51, 23 (45.1%) had received one dose, 4 (7.8%) two doses, and 24 (47.1%) at least three doses (fully vaccinated). In the multivariable Firth penalized logistic regression model, participants who had access to HBV vaccination programs during training were significantly more likely to be vaccinated than those without such programs ( Conclusion: HBV vaccination coverage among volunteer HCWs in Zambia was low. Vaccination programs during training, age and the availability of HBV testing services were important factors associated with vaccine uptake. Strengthening institutional HBV prevention programs may improve vaccination coverage and reduce occupational risk among HCWs.
