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
backgroundLiuzijue is an essential nonpharmacological intervention within the comprehensive management strategies for chronic obstructive pulmonary disease (COPD) patients. However, the absence of an animal model for Liuzijue presents methodological limitations in its basic research. This study aimed to apply interventions with kinematic characteristics of Liuzijue to COPD mice, with the objective to explore an animal model of Liuzijue suitable for experimental studies.
methodsForty-eight C57BL/6 mice randomly assigned into six groups to receive interventions mimicking Liuzijue's kinematic features, namely aerobic exercise, pursed-lip breathing and abdominal breathing. Post-intervention, respiratory function, diaphragmatic contractility, and rectus abdominis thickness were assessed. Histological structures of lung tissue, diaphragm, and rectus abdominis were observed using H&E staining. Expression levels of IL-10, INF-γ, and TNF-α in bronchoalveolar lavage fluid, and p65, CasP3, MuRF1, MyoD1, IGF-1, and Hspa5 in the diaphragm and rectus abdominis were measured.
resultsThe modeling process impaired respiratory function and diaphragmatic contractility in mice. All four stimulation forms effectively improved pulmonary and diaphragmatic function in COPD mice. The thickness of the rectus abdominis was increased by three specified exercise forms. Despite minimal lung tissue structural changes, swimming and abdominal stimulation improved the structure of the rectus abdominis in COPD mice and airway inflammation levels were inhibited. Lastly, the four stimulations regulated the balance of myoprotein synthesis and degradation in the diaphragm and rectus abdominis, although the intervention effects of the four stimulations did not escalate with the complexity of the methods.
conclusionThe exercise stimulation paradigms established by simulating the kinematic characteristics of Liuzijue possess the therapeutic effects of Liuzijue in improving respiratory function, demonstrating first evidence that kinematic-based animal models can bridge traditional Qigong and modern mechanism research. However, the development of an animal model for the application of Liuzijue in basic research still warrants further exploration.
