Effectiveness and Physiological Safety of a Lung Vibration Device for Airway Clearance in Patients with Sputum Retention: A Randomized Crossover Study.
Article in Life (Basel, Switzerland), 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
Lung vibration is a chest physiotherapy technique used to facilitate sputum mobilization and improve airway clearance; however, its effectiveness may vary due to therapist-dependent factors. This study developed a lung vibration device and evaluated its effectiveness in patients with sputum retention. Twenty-five patients, aged ≥18 years with sputum retention, including those with bronchiectasis, pneumonia, and COPD-related conditions, participated in a randomized crossover trial and received two single interventions in random order: a conventional intervention (manual percussion, manual vibration, and suction) and an experimental intervention (manual vibration replaced by the device). Sputum volume and quality, rating of perceived dyspnea (RPD), peripheral oxygen saturation (SpO
