1 · What the graph read from it

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.

2 · The registry

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

objectiveTo systematize and critically analyze scientific evidence on the effects of inspiratory muscle training (IMT) in adults with obesity and obstructive sleep apnea (OSA), focusing on outcomes related to OSA severity, respiratory muscle strength, respiratory function, cardiovascular parameters, sleep quality, and excessive daytime sleepiness.

methodsA systematic literature review was performed, in accordance with PRISMA 2020 guidelines. Searches were conducted in November 2025, across six databases (PubMed, Cochrane Library, SciELO, Scopus, Web of Science, and Embase). The review was registered in PROSPERO (CRD420251057891). Included studies were randomized controlled trials that evaluated the effects of IMT in adults with obesity and OSA.

resultsSix studies were identified that investigated IMT in individuals with OSA and with an average body mass index BMI ≥ 30 kg/m². The primary outcomes assessed included the effects of IMT on maximal inspiratory pressure (MIP), the apnea-hypopnea index (AHI), cardiovascular parameters, excessive daytime sleepiness (EDS), sleep quality, neck and waist circumference, and functional capacity. The studies provided favorable evidence suggesting the use of IMT to improve these parameters, although some results showed inconsistencies.

conclusionAlthough IMT is a low-cost, feasible, and home-based intervention, the current evidence is insufficient to support its recommendation as a standard therapeutic approach. Further high-quality randomized controlled trials with clearly defined obesity-based inclusion criteria and adequate follow-up are required to establish the effectiveness and clinical role of IMT as an adjunctive, non-pharmacological therapy in adults with obesity and OSA.
