Knowledge of Herpes Zoster and Attitudes Toward Vaccination: A Questionnaire-Based Study in Outpatient and Online Settings.
Article in Vaccines, 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
BACKGROUND/
objectivesHerpes zoster (HZ) vaccination rates remain low globally despite the availability of effective recombinant vaccines. This study aimed to assess knowledge of HZ and HZ vaccination, willingness to vaccinate, and factors associated with vaccination willingness among at-risk populations in both outpatient clinic and online survey settings in Poland.
methodsA questionnaire-based cross-sectional study was conducted between May and September 2025 in outpatient primary care clinics operated by Medical Center Medyk (Podkarpackie Voivodeship, southeastern Poland) and via online social media platforms. Participants included individuals aged ≥50 years with a history of HZ and individuals aged ≥18 years with at least one recognised HZ risk factor. Multivariable logistic regression and classification and regression tree (CART) analysis were employed to identify predictors of vaccination willingness.
resultsValid responses were obtained from 212 onsite and 241 online participants. A prior history of HZ was significantly associated with correct responses to several knowledge items concerning HZ and HZ vaccination in both settings. Over 40% of initially hesitant or unwilling onsite participants reported a positive change in vaccination intention following medical consultation. CART models demonstrated good discriminative performance (AUC: online 0.841, onsite 0.861). The primary difference between settings was the source of information: online participants relied more heavily on the internet, whereas onsite participants more frequently cited healthcare professionals.
conclusionsPersonal experience with HZ and engagement with healthcare professionals significantly influence vaccination willingness. Targeted educational interventions delivered through appropriate communication channels, with emphasis on physician engagement, may help improve vaccination willingness among at-risk populations.
