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.

Question: Does single copy of variant CYP2A6 alleles confer susceptibility to liver dysfunction in patients treated with coumarin?
Answer: No evidence was obtained that the studied polymorphism in CYP2A6 is a determinant of the coumarin-associated liver dysfunction.
no

Question: Is resistive heating more effective than metallic-foil insulation in an experimental model of accidental hypothermia : A randomized controlled trial?
Answer: Resistive heating more than doubles the rewarming rate compared with that produced by reflective metal foil and does so without producing an afterdrop. It is therefore likely to be useful in the prehospital setting.
yes

Question: Does mRI-based ACL graft maturity predict clinical and functional outcomes during the first year after ACL reconstruction?
Answer: The MRI-based graft maturity does not have the ability to predict clinical and functional outcomes in patients at the first-year follow-up. Graft maturity should not be used as an objective test to determine the appropriate time to return to sports during the first year after ACL reconstruction. The results from this study will allow clinicians to determine graft-specific health to determine whether the graft is healed enough to return to sports during the first postoperative year.

no
