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.

Example Input: Question: Does successful AV fistula creation lead to higher catheter use : the experience by the Northwest Renal Network 16 Vascular Access Quality Improvement Program . Four years follow-up?
Answer: The success of Network 16's AVF interventions demonstrates the effectiveness of Network education promoting multidisciplinary teamwork, and innovative strategies to increase dramatically AVF use without substantial increase in catheter use.
Example Output: no

Example Input: Question: Do inpatient admission for febrile seizure and subsequent outcomes differ in children with vaccine-associated versus non-vaccine associated febrile seizures?
Answer: The risk of hospitalization for index FS or select subsequent FS outcomes did not differ between VA or NVA-FS. This suggests that the follow-up care of children with VA-FS does not warrant attention beyond that for NVA-FS.
Example Output: no

Example Input: Question: Is the E-selectin S128R polymorphism a risk factor for coronary artery disease in patients with diabetes mellitus type 2?
Answer: In subjects suffering from diabetes mellitus type 2 the E-selectin S128R polymorphism is not associated with coronary artery disease nor with an increased risk for myocardial infarction. Thus, screening for this polymorphism is not indicated for risk assessment of CAD in patients with diabetes mellitus.
Example Output:
no
