Translation and cross-cultural adaptation of the Brazilian version of the Down Syndrome Speech Intelligibility Survey.
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 cross-culturally adapt the "Down Syndrome Speech Intelligibility Survey" questionnaire into Brazilian Portuguese.
methodsThe following steps were taken for cross-cultural adaptation: translation of the instrument from the source language to the target language, synthesis of the translated versions, evaluation of the synthesis by expert judges, evaluation of the instrument by the target audience, back translation, and pilot study.
resultsAfter the translation and synthesis of the translations, most expert judges analyzed almost all instrument items (n = 44, 97.77%) as very relevant, very feasible, and appropriate. In the analysis by the target population, parents suggested changes, improving the understanding of the instrument. The back translation revealed some inconsistencies in the translated and adapted version in relation to the original instrument's content, and the appropriate adjustments were made. The pilot study identified the need to adapt some questions, exclude one item (which had similar content to another), and include prior instructions for completion, resulting in the final instrument version.
conclusionThe translation and cross-cultural adaptation verified the validity evidence based on the content of the Brazilian version of the Down Syndrome Speech Intelligibility Survey.
