Digital engagement and knowledge about zoonoses among dog and cat owners in Rio de Janeiro: a cross-sectional study.
Article in Frontiers in digital health, 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: The One Health approach highlights the interconnectedness between human, animal, and environmental health, reinforcing the importance of public awareness in preventing zoonoses, which remain major sources of emerging infectious diseases. Given the increasing popularity of pet ownership and the widespread use of mobile phones for accessing information, understanding how pet owners engage with digital health content is essential for guiding effective educational strategies. This study assessed the profile of dog and cat owners in Rio de Janeiro, Brazil; their knowledge about zoonoses; patterns of internet and mobile app use; and their interest in a health education app. Methods: A cross-sectional study was conducted with 166 pet owners recruited from a public veterinary clinic and a private service. Data were collected using a REDCap-based questionnaire administered through face-to-face interviews and online surveys. Descriptive statistics and association tests were performed to explore relationships between demographic variables, digital engagement, and knowledge of zoonoses. Results: Most respondents were women (78.3%), aged 18-34 years (51.2%) and had higher education degrees (54.2%). Mobile phones were the primary means of internet access. A total of 85.5% had heard of zoonoses, with rabies (86.7%) and sporotrichosis (35.5%) being the most frequently cited. Although 62.6% reported visiting veterinarians twice or more per year, 18.7% did not seek veterinary care. Only 19.9% used pet-care apps, while 74.7% searched online for animal health information. No significant associations were found between demographic characteristics and zoonosis knowledge, predominant mobile phone use, or app use. Significant associations were observed only between mobile phone users and social media access, information-seeking behaviors, knowledge of zoonoses, and pet-care app use. Conclusion: Mobile phones are the main gateway to health information, indicating strong potential for digital tools to enhance health education and support responsible pet ownership, while respecting veterinarians' exclusive role in diagnosis and treatment.
