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: This study aims to explore the effects of combining phrenic nerve electrical stimulation with respiratory training on pulmonary and trunk function in post-stroke individuals. Rationale for combining these interventions stems from the diaphragm's dual role in respiration and postural control, as well as the limitations of conventional respiratory training in addressing phrenic nerve dysfunction and impaired diaphragm coordination after stroke. Methods: In this single-blinded randomized controlled trial, 160 early stroke patients were randomly assigned via computer-generated random number tables with allocation concealment using sealed opaque envelopes to a control group receiving standard therapy and an experimental group receiving additional phrenic nerve stimulation and breathing training. Each group comprised 80 patients. To evaluate the trunk function and balance before and after the treatment, the Sheikh Trunk Control Scale, Berg Balance Scale (BBS), and Balance Feedback Training Device were utilized. Additionally, pulmonary function was assessed using a pulmonary function measuring instrument. Results: Following 4 weeks of treatment, there was a statistically significant enhancement in the Sheikh Trunk Control Scale and BBS scores, respiratory muscle strength index, and peak inspiratory flow rate for patients in both groups ( Conclusion: Combining phrenic nerve stimulation with respiratory training can effectively improve lung and core functions during post-stroke rehabilitation. However, generalizability is limited by the short follow-up period and strict exclusion criteria. Future research should explore long-term outcomes and compare combined interventions with standalone therapies.
