Deafness and Additional Disabilities Questionnaire: translation and cultural adaptation into Brazilian Portuguese.
Article in CoDAS, 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
purposeTranslate and culturally adapt the Deafness and Additional Disabilities Questionnaire (DAD-Q) into Brazilian Portuguese.
methodsTranslation, back-translation, review by an expert committee, and cultural adaptation were conducted. For the cultural adaptation, 11 mothers of deaf children with additional disabilities, who use cochlear implants, participated. The reliability of the translated instrument was estimated using internal consistency analysis (Cronbach's Alpha). Equivalence was defined as the absence of difficulty in understanding the questions by at least 80% of the participants. The participants also rated the difficulty in responding to the Brazilian Portuguese version of the instrument and the time required for its application.
resultsThe discrepancies in the translation were resolved by the expert committee, and 100% of the participants reported understanding all the questions in the instrument without difficulty. The Cronbach's alpha coefficient demonstrated nearly perfect internal consistency for the instrument and substantial consistency in the other domains. Most participants rated the instrument as "very easy" and "quick" to respond to.
conclusionThe DAD-Q instrument was translated and adapted into Brazilian Portuguese, resulting in the Questionário de Surdez e Deficiências Adicionais (DADQ-PT).
