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 degenerative spondylolisthesis affect the outcome of unilateral laminotomy with bilateral decompression in patients with lumbar stenosis?
Answer: Our study thus indicates that preoperative degenerative spondylolisthesis does not worsen the outcome of patients with lumbar stenosis undergoing unilateral laminotomy with bilateral decompression. These results suggest that lumbar fusion is often unnecessary in patients with degenerative spondylolisthesis and lumbar stenosis if the posterior decompression technique is unilateral laminotomy with bilateral decompression.

Q: Question: Does serum HCV RNA titer predict the severity of liver damage in HCV carriers with normal aminotransferase levels?
Answer: In HCV carriers with normal aminotransferase levels viraemia does not predict the grade of HCV-related chronic liver disease (CLD), although subjects with higher HCV RNA levels seem to have more severe fibrosis. Although these data suggest that patients with higher viraemia might have more intense architectural changes and more severe progression of liver disease than those with lower levels of HCV replication, the weak and imprecise correlation leads us to conclude that HCV RNA quantitation is not a useful indicator in clinical practice in the selection of patients for liver biopsy.

Q: Question: Is interaction of the growth and tumour suppressor NORE1A with microtubules required for its growth-suppressive function?
Answer: The interaction of NORE1A with microtubules is mediated by MAP1B, but not C19ORF5 protein. Interaction of NORE1A with centrosomes is not dependent on C19ORF5 or MAP1B, and appears to involve a different mechanism independent of binding to microtubules. The NORE1A microtubular localization is not required for growth suppression.
