Task: Answer Verification
Input (English): Question: Is younger age associated with lower reactive hyperemic index but not lower flow-mediated dilation among children and adolescents?
Answer: Younger age is associated with lower RHI but not lower FMD among children and adolescents. These findings call into question the validity and usefulness of digital reactive hyperemia as a method to quantify endothelial function among younger children.
Output (English): yes
