Effects of Liuzijue Qigong on respiratory function, trunk control, and balance after stroke: a randomized controlled trial.

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
Purpose: To evaluate the effects of adding Liuzijue Qigong (LQG) to standard rehabilitation on respiratory function, trunk control, and balance after stroke, and to explore a possible respiratory-core-balance pathway. Materials and methods: In this assessor-blinded randomized controlled trial, 120 post-stroke inpatients were randomly assigned (1:1) to LQG plus standard rehabilitation or standard rehabilitation alone for 3 weeks. Primary outcomes were trunk control, assessed by the Trunk Impairment Scale (TIS), and pulmonary function, assessed by forced vital capacity (FVC) and peak expiratory flow (PEF). Secondary outcomes included balance, assessed by the Berg Balance Scale (BBS), affected-side external oblique (EO) surface electromyography (sEMG), forced expiratory volume in 1 s (FEV Results: Both groups showed significant within-group improvements in the TIS and BBS after the 3-week intervention. However, between-group differences in TIS and BBS change scores were not statistically significant ( Conclusion: Adding LQG to standard rehabilitation yielded greater improvements in FVC, PEF, and affected-side EO activation after stroke. Although additional gains in trunk control and balance scales were not statistically significant over 3 weeks, exploratory analyses suggested a possible respiratory-core-balance pathway that warrants further validation.
