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
Objective: The study aims to explore the relationship of vaccination service accessibility, social norms, and perceived usefulness on the intention to get the herpes zoster vaccine (HZV) among middle-aged and older adults, and to provide suggestions for promoting the health and disease prevention of this population. Methods: A questionnaire was developed based on the Stimulus-Organism-Response (SOR) theory. Utilizing stratified random and convenience sampling, the study enrolled participants aged 45 years and above. A structural equation modeling approach was employed to explore the relationships among external factors, perceived usefulness and vaccination intention among the surveyed population. Results: Ultimately, a datasets consisting of 481 valid samples was obtained. Social norms and perceived usefulness were positively associated with the intentions of middle-aged and older adults to receive HZV. Accessibility of vaccination services and social norms were also positively related to perceived usefulness, while accessibility showed no direct correlation with vaccination intention. Perceived usefulness was found to mediate the relationships between both accessibility and social norms with vaccination intention. Conclusion: Social norms and perceived usefulness are significant associated with vaccination intentions. Both vaccination services and social norms were related to vaccination intention through the mediation of perceived usefulness. This study emphasizes the role of perception in external information and willingness to vaccinate. Vaccination management should be strengthened to enhance service accessibility and reduce economic burdens. Promote a social consensus on vaccination to prevent disease. Attention to social norm contents and official channels, coupled with increased perceived usefulness, can further bolster vaccination intentions among adults aged 45 and above.
