No Evidence

How much your heart rate changes might be connected to how your body's automatic systems work, which could relate to fatty liver disease

Scientific Claim

Heart rate variability measured from short electrocardiograms may reflect autonomic nervous system function related to non-alcoholic fatty liver disease development

Evidence Quality Assessment

Claim Status

appropriately stated

Study Design Support

Design supports claim

Appropriate Language Strength

association

Can only show association/correlation

Assessment Explanation

The claim appropriately uses 'may reflect' and does not state the mechanism as proven. It correctly acknowledges the association without claiming causation or mechanism.

Source Excerpt

Low heart rate variability from 10-s electrocardiograms is associated with development of non-alcoholic fatty liver disease

Evidence from Studies

Supporting Evidence (1)

Why it supports

The study demonstrates an association between HRV and NAFLD, and HRV is known to reflect autonomic nervous system function. However, the study does not directly measure or prove this mechanism.
