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 multidisciplinary care improve amputation-free survival in patients with chronic critical limb ischemia?
Answer: MDC pathways for the management of a population of CLI patients improved AFS by greater than twofold and should be the standard of care for the CLI population. Baseline nonambulatory status and unrevascularized patients also predict worse AFS. Wound healing remains prolonged regardless of preoperative or postoperative wound care. Future study is required to evaluate the costs and functional outcomes for MDC in the management of CLI.

Output: yes


Input: Consider Input: Question: Is statin use associated with reduced risk of skin cancer : a meta-analysis?
Answer: Our meta-analysis does not support a potential role of statin use in the prevention of skin cancer.

Output: no


Input: Consider Input: Question: Does high-dose preoperative radiotherapy alter the strength of unilaterally irradiated colon anastomoses in rats?
Answer: After high doses of preoperative radiotherapy, colon anastomoses in rats can be safely constructed if only one anastomotic segment is irradiated. The strength of bilaterally irradiated colon anastomoses is dose-dependent.


Output: no
