Artificial intelligence in Brazilian public health: potential, challenges, and ethical implications for the Brazilian Unified Health System.
Article in Revista brasileira de epidemiologia = Brazilian journal of epidemiology, 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
objectivesTo critically analyze the potential, challenges, and ethical implications of incorporating artificial intelligence (AI) into Brazilian public health, in light of the principles of the Unified Health System (SUS), also considering its interfaces with epidemiological practice.
methodsThis is a theoretical-analytical paper based on national and international literature, which articulates core AI concepts with political-epistemological reflections from Public Health. The approach includes discussions on machine learning, deep learning, natural language processing, and large language models, focusing on applications within the SUS context.
resultsMultiple opportunities for using AI to strengthen the SUS are identified, including prediction of health events, diagnostic support, service regulation, and public policy development. However, structural barriers such as fragmented information systems, regional inequalities, and gaps in professional training are highlighted. Issues such as algorithmic fairness, explainability, technological sovereignty, and digital literacy emerge as key dimensions for the responsible adoption of AI.
conclusionAI is not neutral, and its integration into the SUS must be guided by democratic principles and sensitivity to social vulnerabilities, or it risks reinforcing technocratic and exclusionary models. The struggle over the meaning of innovation is, therefore, also a struggle over the future of public health in Brazil.
