Effectiveness of a Community-Based Social Innovation for Opisthorchis viverrini and Cholangiocarcinoma Prevention in High-Risk Areas of Thailand.
Article in Asian Pacific journal of cancer prevention : APJCP, 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
objectivesThis study aimed to develop and evaluate a community-based social innovation to prevent Opisthorchis viverrini (OV) infection and cholangiocarcinoma (CCA), which are critical public health challenges in northeastern Thailand.
methodsA research and development (R&D) approach was implemented across five provinces in Thailand's 10th Health Region. The intervention, "3 Health for a CCA-Free Society," focused on three domains: Health Behaviors, Health Hygiene, and Environmental Health. A manual-based innovation was co-developed through community engagement and expert collaboration. Using a quasi-experimental pre-post design, its effectiveness was evaluated in a prototype area that was randomly selected from the five provinces (n = 56). Structured questionnaires assessed participants' knowledge, health beliefs, and preventive behaviors. Paired t-tests and Wilcoxon signed-rank tests were applied to evaluate changes. Satisfaction was assessed using the Context, Input, Process, and Product (CIPP) model.
resultsStatistically significant improvements were found in knowledge (mean increase = 0.47, p < 0.001), health beliefs (mean increase = 3.92, p < 0.001), and preventive behaviors (mean increase = 3.07, p < 0.001). Satisfaction scores were high across all CIPP domains (mean = 4.88 ± 0.26). The manual was rated clear, relevant, and culturally appropriate, indicating strong potential for broader application.
conclusionThis community-based social innovation significantly improved OV and CCA prevention outcomes in a high-risk area. The approach is feasible, scalable, and aligned with national strategies for participatory disease prevention. Further studies should explore its long-term impact and the potential for digital adaptation for broader dissemination.
