Translation and cultural adaptation of the Short Version of the Reflux Symptom Score: Reflux Symptom Score-12 into Brazilian Portuguese.

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
objectiveTo describe the process of translation into Brazilian Portuguese and cross-cultural adaptation of the French Reflux Symptom Score-12 questionnaire used for the diagnosis of laryngopharyngeal reflux.
methodsThis was a cross-cultural translation and adaptation study of a health instrument, with a cross-sectional design. It was carried out in eight stages: translation from French into Brazilian Portuguese, cultural adaptation by a panel of experts, application of the first version (pilot test 1), adaptation by a panel of experts, application of the second version (pilot test 2), back translation, reviewing by a committee in conjunction with the author of the original instrument and, application of the final version. The Brazilian Portuguese versions of the questionnaire were applied to individuals with symptoms and signs of laryngopharyngeal reflux who underwent pHmetry and esophageal manometry at the study site.
resultsIn pilot test 1, the first version of the RSS-12 in Brazilian Portuguese was applied to 30 patients. The patients had no difficulty to understand any of the 12 symptom items, but 15 patients (50%) had difficulty interpreting the symptom frequency score. After adapting the format of the frequency score, a version 2 of the RSS-12 in Brazilian Portuguese was applied to another 23 patients, who completed the questionnaire in full without any difficulty. Along with the review committee, the author of the original RSS-12 considered the version 2 to be adequate and did not propose any changes, so it was approved as the final version of the Brazilian Portuguese RSS-12.
conclusionThe Brazilian Portuguese version of the instrument, called Reflux Symptom Score-12 PT-BR, shows good understanding and linguistic, conceptual and content equivalence, in relation to the original Reflux Symptom Score-12.
