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: Consider Input: Question: Is planimetry of aortic valve area using multiplane transoesophageal echocardiography a reliable method for assessing severity of aortic stenosis?
Answer: Planimetry of aortic valve area by TOE is difficult and less accurate than the continuity equation for assessing the severity of aortic stenosis.

Output: no


Input: Consider Input: Question: Does transdermal oxygen improve sternal wound oxygenation in patients recovering from cardiac surgery?
Answer: Additional inspired oxygen improved Pao(2) and sternal wound PsqO(2) after bypass and may, consequently, reduce infection risk. However, oxygen insufflated locally into an occlusive dressing did not improve wound PsqO(2) and, therefore, does not appear to be useful clinically in cardiac surgery patients to reduce sternal wound infections.

Output: no


Input: Consider Input: Question: Does the preoperative neutrophil/lymphocyte ratio correlate with the 21-gene recurrence score in estrogen receptor-positive breast cancer patients?
Answer: Our data suggest that the preoperative NLR does not predict the 21-gene RS in patients with early-stage hormone-sensitive BC.


Output: no
