Developing a digital interactive tool to enhance cervical cancer awareness and health literacy in Croatia: a community case study.
Article in Frontiers in public 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: Cervical cancer is highly preventable but remains a major public health problem due to limited health literacy and suboptimal uptake of HPV vaccination and screening. Digital health tools are increasingly used to provide risk communication and prevention information. Objective: To describe the development, implementation, and early use of a free web-based tool for cervical cancer risk self-assessment in Croatia and to report initial usage metrics from this community-based initiative. Methods: An interdisciplinary team translated published evidence on cervical cancer risk factors into a decision-tree-based scoring system embedded in an online questionnaire featuring conditional logic and tailored feedback. Risk categories and thresholds were derived from literature-informed estimates and expert consensus and have not yet been empirically validated against clinical outcomes. The tool was deployed on the national "Neću rak" ("I Don't Want Cancer") platform of the Croatian Institute of Public Health. Aggregated, anonymized usage data from February 2023 to February 2025 were analysed descriptively. Results: The questionnaire (10-14 items, depending on branching logic) categorises users into four qualitative risk levels (no, low, moderate, high). In the first two years, the tool was accessed almost 9,000 times, with about 8,000 completed questionnaires, indicating a high completion rate. Most respondents (around 60%) were aged 34-54 years. Self-reported HPV vaccination (13%) and smoking history (30%) reflect aggregated responses from voluntary users and do not represent the general population. Conclusion: This national web-based risk calculator demonstrates the feasibility of integrating evidence-informed scoring framework and tailored educational content within a public health platform. Such digital tools may contribute to awareness and support existing screening and vaccination programmes. However, formal evaluation of algorithm performance, usability, and potential behavioural impact is required before effectiveness can be determined.
