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
objectiveDespite the high prevalence of rheumatic heart disease in Brazil, the occurrence of functional impairment in children and adolescents with rheumatic heart disease is not clear. The aim of this study was to evaluate exercise tolerance, respiratory muscle strength, lung function, and quality of life of children and adolescents with rheumatic heart disease.
methodsCross-sectional study, conducted from August to December 2014 with children and adolescents with rheumatic heart disease aged 8 to 16 years. The participants, after completing the socioeconomic, clinical, and quality of life questionnaires were tested by spirometry, manovacuometry and in a 6-minute walk test. The variables and their reference values were compared using the paired Student's t-test. Comparisons between predicted and observed walking distance were done also by Student's t-test, consdiering the categorization of the participants. Correlations between these differences and quantitative variables were assessed by Pearson's coefficient, being significant p<0.05.
resultsAll 56 participants had a walked distance lower than predicted (p<0.001). The differences between predicted and observed distances were positively correlated with the baseline heart rate (r=0.3545; p=0.007). Expiratory muscle strength was also lower than the predicted values (p<0,001). Regarding quality of life assessment, the mean scores were 70, 77 and 67% for general, physical, and psychosocial aspects, respectively.
conclusionsChildren and adolescents with rheumatic heart disease have reduced exercise tolerance, which is related to their higher baseline heart rate; they also show impaired expiratory strength and quality of life.
