Acute effects of inspiratory muscle training at different intensities in healthy young people.
Article in Irish journal of medical science, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. It is linked to 2 registered trials, which are not on this map. Cited by 9 papers, 2 of them syntheses that pooled 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.
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.

Abstract
backgroundUnderstanding the acute effects of inspiratory muscle training (IMT) at different intensities on the autonomic nervous system, arterial stiffness, and blood pressure in healthy young people will be important in the constitution of appropriate IMT prescriptions.
aimsTo investigate the acute effects of IMT at different intensities on autonomic function, arterial stiffness, and blood pressure in healthy young people
methodsThirty-six healthy participants were enrolled in this crossover study. All participants randomly performed IMT sessions, which consisted of diaphragmatic breathing exercise (DBE), 10%, 30%, and 60% of maximal inspiratory pressure (MIP) on consecutive days. Autonomic function and arterial stiffness were assessed by measuring heart rate variability (HRV) and aortic pulse wave velocity (AoPWV), respectively. HRV, AoPWV, and blood pressure were recorded before and immediately after each IMT session.
resultsThere was no significant difference in the baseline measurements between IMT sessions (p > 0.05). Heart rate (HR) significantly decreased after DBE and IMT at 10% of MIP (p < 0.05). All time domain parameters of HRV significantly improved after DBE compared with the baseline (p < 0.05). There was no difference in the frequency domain of HRV after the IMT sessions (p > 0.05). AoPWV significantly increased after IMT at 60% of MIP (p < 0.05). Mean arterial pressure significantly changed after DBE and IMT at 60% of MIP (p < 0.05).
conclusionsA single session of DBE positively affects autonomic function and blood pressure, while IMT at 60% of MIP increases arterial stiffness. The different intensities of IMT have various impacts on autonomic function, arterial stiffness, and blood pressure.
