Instructions: Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.
Input: Question: Does invasive aortic pulse wave velocity as a marker for arterial stiffness predict outcome of renal sympathetic denervation?
Answer: Patients with lower pulse wave velocity showed a significantly better response to denervation. These findings emphasise that pulse wave velocity might be used as a selection criterion for renal denervation.
Output:
yes
