The effect of respiratory training on lung function in intensive care unit patients: a systematic review and meta-analysis.
Synthesis in BMC pulmonary 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
backgroundMechanically ventilated patients in the intensive care unit (ICU) usually develop respiratory muscle wasting atrophy, causing pulmonary dysfunction. The benefits of respiratory muscle training (RMT) on pulmonary function recovery have been demonstrated, but whether it is effective in patients following mechanical ventilation in the ICU has not been proven. This study aimed to evaluate the effectiveness of RMT on lung function and mechanical ventilation duration in ICU patients, addressing the lack of comprehensive evidence on its benefits for mechanically ventilated individuals.
methodsThis systematic review and meta-analysis was conducted on the databases from PubMed, Cochrane Library, Web of Science, and Embase. The search period was extended to 30th April 2025. Studies included ICU patients receiving RMT, and outcomes such as maximum inspiratory pressure (MIP), forced vital capacity (FVC), and mechanical ventilation duration were analyzed using RevMan software. Heterogeneity was assessed using I² statistics.
results18 randomized controlled trials (RCTs) were included for analysis. RMT significantly improved MIP (SMD: 0.88, 95% CI: 0.53–1.24) and FVC (SMD: 0.32, 95% CI: 0.07–0.58) and reduced mechanical ventilation duration by 0.88 days (95% CI: -1.10 to -0.66).
conclusionsRespiratory muscle training enhances lung function and shortens mechanical ventilation duration in ICU patients, supporting its early implementation as a rehabilitation strategy.
