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: Does a cytotoxic phenotype predict clinical outcome in anaplastic large cell lymphomas?
Answer: In primary biopsies of patients with ALCL, the presence of a cytotoxic phenotype is not related to clinical outcome of the disease.

Output: no


Input: Consider Input: Question: Does [ Histology accurately predict the clinical behaviour of bronchopulmonary carcinoids - results from an Icelandic population-based study ]?
Answer: BPCs usually behave as benign neoplasms, with excellent long-term survival after surgical removal. Metastases are more common in patients with atypical histology (40%), and their survival is worse. However patients with typical histology can metastasize (14.8%) and die from the disease. Therefore, histology (typical vs. atypical) can not be used with certainty to predict the clinical behaviour of these tumors.

Output: no


Input: Consider Input: Question: Does percutaneous intervention for carotid in-stent restenosis improve outcomes compared with nonoperative management?
Answer: Over 13 years, percutaneous interventions for ≥50% C-ISR were safe and durable. However, interventions fail to improve long-term stroke/death/MI or patency rates relative to nonintervention. Intervention for C-ISR may not be necessary, although future appropriately powered, prospective trials will be necessary to confirm these findings and to determine the appropriateness of interventions for C-ISR.


Output: no
