Key result
A significant positive correlation was found between sympathetic amplitude response and body mass index (p = 0.000377) using a novel template matching algorithm to quantify autonomic function.
Why the study?
Reliable, sensitive, and quantitative biomarkers defined in healthy individuals were needed to discriminate clinically useful changes in autonomic nervous system function.
Can an algorithmic approach extracting multimodal responses from standard autonomic tests reliably quantify autonomic nervous system function in healthy individuals?
Observational (n=21)
No
Can an algorithmic approach extracting multimodal responses from standard autonomic tests reliably quantify autonomic nervous system function in healthy individuals?
p-value: p=0.000377
A novel algorithmic approach using standard noninvasive autonomic tests can reliably quantify autonomic nervous system function and correlates with BMI in healthy individuals.
No takes yet. Share an insight, caveat, or question.
Should not change practice; leaves open whether template matching enhances autonomic quantification in patients.
Debnath et al. (2021) conducted an observational in Healthy (n=21). Standard clinical autonomic tests (squat test, cold pressor test, diving reflex test, deep breathing, Valsalva maneuver) was evaluated on Correlation between sympathetic amplitude response and body mass index (p=0.000377). A significant positive correlation was found between sympathetic amplitude response and body mass index (p = 0.000377) using a novel template matching algorithm to quantify autonomic function.
