A secondary analysis of autonomic function during high-intensity interval exercise in adults with chronic stroke.
Article in Physiological reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Autonomic dysfunction post-stroke negatively affects the cardiovascular system's ability to regulate heart rate and blood pressure response to exercise. While high-intensity interval exercise (HIIE) is prescribed for stroke recovery, limited knowledge exists regarding how HIIE impacts autonomic function post-stroke. Characterize autonomic nervous system response to HIIE post-stroke. Heart rate and blood pressure were recorded during a 10-min recumbent stepper HIIE bout, cool-down, immediately post-exercise, and 30-min post-exercise. Fast Fourier Transformation was used to determine low and high frequency beat-to-beat blood pressure and heart rate power spectral density at all timepoints and baseline baroreflex sensitivity. We tested for differences in spectral data between timepoints using Friedman's test. The influence of arterial stiffness, age, and beta-blocker use on autonomic function was explored using linear regression. Twenty-seven participants completed HIIE. The autonomic nervous system response to HIIE was blunted with neither low nor high frequency blood pressure or heart rate variability exhibiting significant changes from baseline during exercise (p > 0.05). Baroreflex sensitivity was impaired, with age (p = 0.03), arterial stiffness (p < 0.01), and beta-blocker use (p = 0.03) affecting sensitivity. Autonomic function is blunted during HIIE post-stroke and likely attributed to impaired baroreflex sensitivity and arterial stiffness.
