Development of an ICF Core Set for adults with Chagas disease: a qualitative study capturing patients' perspective on functioning.

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
backgroundChagas disease affects multiple dimensions of human functioning, requiring assessments that extend beyond the biomedical model. The International Classification of Functioning, Disability and Health (ICF) offers an integrative framework for capturing these impacts. This qualitative study aimed to identify, from the perspective of adults diagnosed with Chagas disease, the aspects of functioning most relevant to them, as a step toward developing an ICF Core Set for this population.
methodsThirteen focus group discussions were conducted with adults diagnosed with Chagas disease, covering all ICF components. Two independent researchers extracted meaningful concepts from verbatim transcripts and linked them to ICF categories.
resultsThirty-two adults with Chagas disease participated. From the discussions, 248 concepts were identified and linked to 49 second-level ICF categories: 13 related to body functions, 5 to body structures, 18 to activities and participation, and 13 to environmental factors. The most frequently mentioned categories were sleep, pain, emotional functions, and cardiac functions. In the Activities and Participation component, limitations were noted in household tasks, mobility, and social participation, with spirituality emerging as a key coping resource. For Environmental Factors, immediate family support and access to healthcare services were identified as primary facilitators of functioning.
conclusionAdults with Chagas disease reported impairments across a wide range of body functions and activities, underscoring the significant influence of environmental factors. The identified categories will serve as a foundation of candidate items to support the consensus process for developing an ICF Core Set for adults with Chagas disease.
