Exploring the Association between Health Literacy and Diabetes Risk in Adults: Insights from a Pilot Study in Leiria.
Article in Portuguese journal of public health, 2025. 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
Introduction: Low levels of health literacy (HL) are related to behaviors that increase the risk of developing type 2 diabetes (T2D). However, in Europe, there is still little knowledge about this relationship, and whether improving HL could be an effective strategy for preventing the disease. Therefore, this study aims to measure the association between HL and the risk of developing T2D in adults living in the municipality of Leiria. Methods: Data from the Longitudinal Health Literacy Study of the Municipality of Leiria were used. The sample (pilot study) consists of 175 individuals aged 18 or over. The Finnish Diabetes Risk Score was used to determine an individual's risk of developing T2D. The short version of the European Health Literacy Questionnaire was applied to assess participants' HL levels. Descriptive statistics were calculated to describe participants' sociodemographic characteristics (sex, age, education, and monthly income). The analysis of the relationship between the level of HL and FINDRISC score was performed using a multivariate linear analysis. The analysis was conducted in three nested statistical models, and adjusted for age, sex, and educational level. Results: According to the FINDRISC, 35.7% of respondents have a low risk, 26.8% a slightly moderate risk, 8.3% a moderate risk, 24.2% a high risk, and 5.1% a very high risk of developing T2D diabetes in the next 10 years. In the statistical model adjusted for age, sex, and education, individuals with inadequate levels of HL presented an average of 4.62 points more on the FINDRISC scale than individuals with excellent levels of HL (95% confidence interval: 0.558-8.677). Discussion/Conclusion: The risk of developing T2D is increased in people with lower levels of HL. It is important to invest in public health programs that empower citizens with knowledge to better manage their health.
