People whose hearts don't change rate as much are more likely to develop fatty liver disease than people whose hearts change rate more
Scientific Claim
Individuals with lower heart rate variability have higher incidence of non-alcoholic fatty liver disease compared to those with higher heart rate variability
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 uses 'associated with' and correctly describes the direction of the relationship without implying causation.
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)
The study found a statistical association between lower HRV and higher NAFLD incidence. The study design supports this correlational claim but cannot determine causation.
