1 · What the graph read from it

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.

2 · The registry

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

backgroundSocial media platforms like Facebook are increasingly used for health communication, particularly for the prevention of non-communicable diseases (NCDs). This study evaluates the use of health communication theories and strategies in Facebook campaigns in Sri Lanka organized by the entities of the Ministry of Health.

methodsA two-phase approach was used. First, a literature review identified suitable theories and strategies to create an evaluation framework. Second, 15 Facebook posts from Sri Lanka’s NCD Unit, Health Promotion Bureau (HPB), and Ministry of Health were analyzed. Data were evaluated based on a scoring system to assess the application of health communication theories and strategies.

resultsThe Health Belief Model (HBM), a psychological model that explains and predicts health behaviors by focusing on individual perceptions of health risks and benefits, and the Social Marketing Mix (SMM) and Lasswell’s 5W, were identified as the most popular and comprehensive theories and strategies in health communication. Results showed strong strategic use, including audience targeting and content structure, but the use of health communication theories, such as HBM, is minimal. Posts aligned well with the Social Marketing Mix and Lasswell’s 5W model. Animated videos showed the best theoretical alignment, but engagement was low unless posts were boosted with paid promotions. Content on physical inactivity was underrepresented.

conclusionsFacebook posts used strategies but lacked strong theoretical foundations. Training content creators to include theory-based approaches and balancing theory with strategy can improve the quality of health communication. This study highlights the need for better policies, training programs, and further research to make social media a more powerful tool in preventing NCDs.
