Comparative efficacy of digital health interventions and traditional mind-body exercises for pulmonary rehabilitation in chronic obstructive pulmonary disease: a systematic review and network meta-analysis.
Synthesis in Frontiers in medicine, 2026. 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
Background: Digital health interventions (DHIs) and traditional mind-body exercises (TMBEs) have shown potential benefits for pulmonary rehabilitation in stable COPD, but their comparative efficacy remains unclear. Objective: To compare DHIs (Synchronous telerehabilitation, Composite digital interventions) and TMBEs (Tai Chi, Baduanjin, Yoga) for stable COPD using network meta-analysis. Methods: PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang, and VIP were searched from inception to April 2026. RCTs comparing DHIs or TMBEs with usual care were included. Bayesian network meta-analysis and network meta-regression were performed. Outcomes included 6MWD, FEV1, FVC, SGRQ and CAT. Treatment effects were expressed as mean differences (MDs) with 95% credible intervals (CrIs), and treatment ranking probabilities and certainty of evidence were assessed using SUCRA and GRADE, respectively. Results: Forty-seven RCTs enrolling 4,720 stable COPD patients were included. Compared with usual care, Baduanjin and Yoga significantly elevated 6MWD, FEV1 and FVC. Tai Chi and Baduanjin produced meaningful SGRQ reductions; four interventions (Baduanjin, Composite digital interventions, Synchronous telerehabilitation, Tai Chi) yielded significant CAT score improvements. SUCRA results revealed Yoga possessed the highest likelihood of top ranking for exercise capacity (6MWD:82.9%) and lung function (FEV1: 90.5%; FVC: 100.0%), with Baduanjin second for FVC (74.8%). Tai Chi ranked best for quality-of-life indicators (SGRQ: 80.7%; CAT: 92.3%). These rankings stemmed mostly from indirect comparisons and cannot confirm definitive superiority between active interventions. Meta-regression indicated longer intervention duration correlated with larger 6MWD improvements. Conclusion: Targeted mind-body exercises and synchronous telerehabilitation exert beneficial effects vs. usual care for stable COPD. Yoga is most likely optimal for exercise endurance and lung function, while Tai Chi performs best for symptom-related quality of life. These rankings rely heavily on indirect evidence and fail to prove clear superiority of any single intervention. Baduanjin shows consistent benefits across all measured outcomes; Synchronous telerehabilitation serves as a viable choice for alleviating respiratory symptoms. Composite digital interventions require more high-quality trials to verify their clinical value.
