Altered autonomic cardiovascular function in adults with persisting post-concussive symptoms and exercise intolerance.
Article in Physiological reports, 2025. 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
Alterations in autonomic cardiovascular function may result following mild traumatic brain injury (mTBI), but there is a lack of data evaluating autonomic function in adults with persisting post-concussive symptoms (PPCS). We collected resting measures of heart rate (HR), heart rate variability (HRV), blood pressure (BP) and cardiac baroreceptor sensitivity in 50 adults with PPCS (42.8 (11.0) years; 24.5 (14.2) months post-injury; 74% female) and 50 age/sex-matched controls (43.0 (11.1) years; 74% female) with no lifetime mTBI history. HR and BP data were collected for ≥4 min when seated and standing. Between-group differences (PPCS vs. control) were analyzed using linear regression. In the seated posture, participants with PPCS had significantly lower HRV than controls, specifically RMSSD (root mean squared of successive RR interval differences) (mean difference = -10.450, p = 0.001) and SDNN (standard deviation of RR intervals) (mean difference = -12.875, p = 0.001). In the standing position, PPCS had lower SDNN. Participants with PPCS had significantly lesser change in HRV, including RMSSD (mean difference = 5.981, p = 0.007) and LF/HF (low-frequency to high-frequency ratio) (mean difference = -2.229, p = 0.016), when going from seated to standing compared to controls. Findings suggest adults with PPCS have altered autonomic function relative to controls. Physical activity level and deconditioning are potential treatment targets to improve autonomic function.
