Breathing retraining for dysfunctional breathing in asthma: a randomised controlled trial.
Trial report in Thorax, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07397676 (Effects of Breathing Technique Training and Physical Activity Counseling on Quality of Life, Symptoms, Asthma Control, and Physical Activity in Children and Adolescents With Asthma), which is not on this map. Cited by 48 papers, 3 of them syntheses that pooled it.
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.

Abstract
backgroundFunctional breathing disorders may complicate asthma and impair quality of life. This study aimed to determine the effectiveness of physiotherapy based breathing retraining for patients treated for asthma in the community who have symptoms suggestive of dysfunctional breathing.
methods33 adult patients aged 17-65 with diagnosed and currently treated asthma and Nijmegen questionnaire scores > or =23 were recruited to a randomised controlled trial comparing short physiotherapy breathing retraining and an asthma nurse education control. The main outcome measures were asthma specific health status (Asthma Quality of Life questionnaire) and Nijmegen questionnaire scores
resultsOf the 33 who entered the study, data were available on 31 after 1 month and 28 at 6 months. The median (interquartile range) changes in overall asthma quality of life score at 1 month were 0.6 (0.05-1.12) and 0.09 (-0.25-0.26) for the breathing retraining and education groups, respectively (p=0.018), 0.42 (0.11-1.17) and 0.09 (-0.58-0.5) for the symptoms domain (p=0.042), 0.52 (0.09-1.25) and 0 (-0.45-0.45) for the activities domain (p=0.007), and 0.50 (0-1.50) and -0.25 (-0.75-0.75) for the environment domain (p=0.018). Only the change in the activities domain remained significant at 6 months (0.83 (-0.10-1.71) and -0.05 (-0.74-0.34), p=0.018), although trends to improvement were seen in the overall score (p=0.065), the symptoms domain (p=0.059), and the environment domain (p=0.065). There was a correlation between changes in quality of life scores and Nijmegen questionnaire scores at 1 month and at 6 months. The number needed to treat to produce a clinically important improvement in health status was 1.96 and 3.57 at 1 and 6 months.
conclusionOver half the patients treated for asthma in the community who have symptoms suggestive of dysfunctional breathing show a clinically relevant improvement in quality of life following a brief physiotherapy intervention. This improvement is maintained in over 25% 6 months after the intervention.
