Translation and Cross-Cultural Adaptation of The Cancer Dyspnoea Scale - CDS 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
purposeTo translate and cross-culturally adapt The Cancer Dyspnoea Scale - CDS into Brazilian Portuguese.
methodsThe original instrument in English was translated by a Brazilian Speech-Language Pathologist (SLP) and a Brazilian translator, both bilingual. The compiled version of the two translations was back-translated by a second SLP and a second translator, both bilingual, native English speakers, and fluent in Brazilian Portuguese. The final version was analyzed by a committee of experts, resulting in the final version of the Escala de Dispneia Oncológica - CDS-Br. It was pre-tested by applying the translated scale (with the additional option of responding "not applicable") to 40 cancer patients with dyspnea complaints - 35 initial participants and another five to confirm subsequent adjustments.
resultsNone of the 35 initial study participants marked "not applicable" in the 12 scale items, but some questions were raised regarding the response keys, which were adapted after the committee of experts rediscussed them. Five new participants then responded to the scale to confirm the adjustments, without the need for further adaptations in the formulation of the items.
conclusionThe translated and cross-culturally adapted version for Brazilian Portuguese was called Escala de Dispneia Oncológica - CDS-Br. Adjustments were necessary during translation and cross-cultural adaptation to reflect the original version and be compatible with the target language and culture. The Escala de Dispneia Oncológica - CDS-Br proved to be an easy-to-apply and understand self-assessment tool for dyspnea in cancer patients.
