Health literacy profiles of riverine populations in the Brazilian Amazon: a cluster analysis.
Article in BMC 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
backgroundHealth literacy is essential for individuals to access, understand, assess, and use health-related information. In riverside communities in the Brazilian Amazon, social vulnerability and difficult access to services make it urgent to understand how these communities deal with health information in their daily lives.
objectiveTo identify the health literacy profiles of riverine communities in the Amazon region of Pará, northern Brazil.
methodsThis is a descriptive, cross-sectional study with 200 residents of the islands of Cotijuba and Combú in the state of Pará, Brazil, in 2024. A multidimensional questionnaire was used to assess health literacy. Cluster analysis allowed the identification of profiles with similar characteristics. The groups were described based on sociodemographic data, lifestyle, and performance on the nine assessed scales, and were named according to their main characteristics.
resultsSeventeen distinct profiles were identified. The greatest differences lie in the dimensions related to social support, to the search for reliable information, and to the ability to use healthcare services.
conclusionsThe heterogeneity in health literacy on the islands points to the need for targeted interventions, especially regarding navigating the system and understanding health information.
