Effectiveness of Paced Breathing Guided by Biofeedback on Clinical and Functional Outcomes Patients with Chronic Obstructive Pulmonary Disease: An Uncontrolled Pilot Study.
Article in Applied psychophysiology and biofeedback, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
To investigate the effectiveness of paced breathing guided by biofeedback on clinical and functional outcomes of patients with chronic obstructive pulmonary disease (COPD). An uncontrolled pilot study comprising a training with paced breathing guided by biofeedback (three sessions of 35 min per week) was conducted over four weeks (12 sessions). Assessments included respiratory muscle strength (using a manovacuometer), anxiety (Beck Anxiety Inventory), depression (Beck Depression Inventory), dyspnea (Baseline Dyspnea Index), functionality (Timed Up and Go Test), health status (COPD Assessment Test) and health-related quality of life (Saint George's Respiratory Questionnaire). The sample consisted of nine patients with a mean age of 68.2 ± 7.8 years. After intervention, patients significantly improved in health status and health-related quality of life, assessed using the COPD Assessment Test (p < 0.001) and Saint George's Respiratory Questionnaire (p < 0.001); anxiety (p < 0.001); and depression (p = 0.001). Patients also significantly improved in dyspnea (p = 0.008), TUG (p = 0.015), CC Score (p = 0.031), and maximum inspiratory (p = 0.004) and expiratory pressures (p < 0.001). An intervention with paced breathing guided by biofeedback promoted positive results on dyspnea, anxiety, depression, health status and perceived health-related quality of life in patients with COPD. Moreover, gains in respiratory muscle strength and functional performance were observed, affecting the performance of daily activities.
