Translation, cultural adaption, and measurement properties of the Brazilian Portuguese version of the dialysis patient-perceived exercise benefits and barriers scale (DPEBBS-BP).
Article in Brazilian journal of physical therapy. 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
objectiveTo translate, culturally adapt, and evaluate the measurement properties of the Dialysis Patient-Perceived Exercise Benefits and Barriers Scale (DPEBBS) in people on hemodialysis in Brazil.
designThis methodological study adhered to COSMIN recommendations.
methodsA multi-method approach: (1) the translation and cultural adaptation, and (2) a cross-sectional survey in people on hemodialysis to assess measurement properties. Factor structure was assessed through confirmatory factor analysis. Convergent validity was tested using Pearson or Spearman correlations. Internal consistency was estimated with Cronbach's alpha (α) and test-retest reliability with Intraclass Correlation Coefficient (ICC). Measurement error was evaluated through the Standard Error of Measurement (SEM) and the minimal detectable change (MDC).
resultsAfter translating, seven experts determined that the Brazilian Portuguese version of the Dialysis Patient-Perceived Exercise Benefits and Barriers Scale (DPEBBS-BP) was applicable. Additionally, the inclusion of six items was suggested. In the evaluation of measurement properties, 299 participants were included (57.2 ± 15.3 years, 64% male). Confirmatory factor analysis produced a seven-factor solution, which represented 59% of the explained variance of the construct. For convergent validity, the barriers score showed moderate correlations with the Duke Activity Status Index (DASI) and with the functional capacity domain of the SF-36. The internal consistency for benefits was α = 0.87, and barriers α = 0.80. The ICC for benefits and barriers was 0.90 and 0.81, respectively. The SEM and MDC for the benefits were 1.83 and 5.07, while 2.70 and 7.50 for the barriers.
conclusionThe DPEBBS was translated and adapted to Brazilian Portuguese and presented adequate measurement properties.
