Adaptation and validation of the Chinese version of Dyspnoea-12 scale in individuals with chronic obstructive pulmonary disease.

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
introductionDyspnoea-12 scale is a validated assessment tool, capturing the perception of dyspnoea and its physical and affective effects in individuals with chronic obstructive pulmonary disease (COPD). A validated version for the Chinese-speaking population has been unavailable.
objectiveTo develop a Chinese version of D-12 (D-12-C) scale and evaluate its validity and reliability.
methodsD-12 was translated from English to traditional Chinese in collaboration with a physician and a linguist. Back translation was adopted to ensure accuracy of the translation. A total of 155 COPD patients were recruited to test the reliability and validity of the D-12-C scale. Internal reliability and test-retest reliability were measured with Cronbach's alpha coefficient and intra-class correlation coefficient, respectively. Construct validity was assessed through exploratory factor analysis (EFA). Concurrent validity was assessed by the correlation of D-12-C total score and sub-scores and the Chinese version of Saint George's Respiratory Questionnaire (SGRQ), 36-Item Short Form Health Survey (SF-36), COPD Assessment Test (CAT) and Hospital Anxiety and Depression Scale (HADS) total score and sub-scores.
resultsThe two-factor structure of D-12-C was confirmed by EFA. D-12-C and its sub-scores demonstrated high level of internal reliability (Cronbach's alpha = 0.88) and moderate level of test-retest reliability. D-12-C total score, physical and affective sub-scores were significantly correlated to SGRQ total score (r
conclusionD-12-C scale was developed, which demonstrated satisfactory reliability and validity in measuring dyspnoea among COPD patients.
