Effectiveness of traditional Chinese Medicine Breathing-Daoyin Rehabilitation Techniques on lung function and exercise endurance in COPD: a systematic review and meta-analysis.

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
Objective: To evaluate the effects of Traditional Chinese Medicine Breathing-Daoyin Rehabilitation Techniques (TCM-BDRT) on lung function and exercise capacity in patients with chronic obstructive pulmonary disease. Methods: We conducted a comprehensive search of Chinese and English databases up to August 2025. Primary outcome measures included pulmonary function parameters (FEV1%, FVC%, PEF%, FEV1/FVC%) and exercise endurance (6-min walk test, 6MWT). Secondary outcomes comprised Chronic Obstructive Pulmonary Disease Assessment Test (CAT) scores, blood gas variables, and incidence of adverse events. Meta-analysis was performed using Stata 17.0. Results: Eleven RCTs involving 964 participants were included. The meta-analysis demonstrated that Traditional Chinese Medicine Breathing-Daoyin Rehabilitation Techniques significantly improved FEV1% [MD = 5.00, 95% confidence interval (2.95, 7.05)], FVC% [MD = 6.34, 95% CI (4.04, 8.63)], peak expiratory flow rate percentage [MD = 6.55, 95% CI (4.93, 8.18)], and 6-min walk distance [MD = 19.53 m, 95% CI (7.94, 31.12)]. It also reduced arterial blood carbon dioxide partial pressure [MD = -5.99, 95% CI (-8.28, -3.69)] and increased arterial oxygen partial pressure [MD = 11.06, 95% CI (8.84, 13.28)]. All differences were statistically significant. No significant differences were observed in improvements in FEV1/FVC% or CAT scores. None of the included studies reported adverse events. The certainty of evidence was moderate to low. Conclusion: TCM-BDRT holds promise as a potential non-pharmacological intervention for enhancing lung function, exercise endurance, and gas exchange capacity in patients with COPD. This low-intensity, scalable therapeutic approach aligns with the integrated treatment paradigm of combining Traditional Chinese Medicine and Western Medicine. It may be particularly suitable for patients who are frail or have limited exercise capacity. Nevertheless, large-scale, multi-center, high-quality RCTs are warranted to validate its long-term efficacy, with a specific focus on safety profiles.
