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.

[Q]: Question: Does patellar taping change the amplitude of electromyographic activity of the vasti in a stair stepping task?
Answer: The results of this study indicate that the positive clinical effects of medially directed therapeutic tape are not due to changes in EMG amplitude of the vasti muscle. Thus other effects such as changes in timing of contraction of the vasti are more likely candidates for the mechanism of efficacy.
[A]: no


[Q]: Question: Do changes in basophil activation during grass-pollen sublingual immunotherapy correlate with clinical efficacy?
Answer: Allergen reactivity of peripheral blood basophils is not a biomarker for adverse events or early onset of clinical responses to SLIT.
[A]: no


[Q]: Question: Does prevention of ischemic mitral regurgitation influence the outcome of remodeling after posterolateral myocardial infarction?
Answer: Prophylactic ventricular restraint reduces infarct expansion, attenuates adverse remodeling, and reduces IMR severity. Prevention of IMR by prophylactic ring annuloplasty does not influence remodeling. Ischemic mitral regurgitation is a consequence, not a cause, of postinfarction remodeling; infarct expansion is the more important therapeutic target.
[A]:
no
