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.

[EX Q]: Question: Does preinjury beta blocker usage affect the heart rate response to initial trauma resuscitation?
Answer: Preinjury beta blockade is associated with a slower presenting heart rate, more bradycardia, less tachycardia, but no difference in mortality or ability to achieve a normal heart rate with resuscitation.
[EX A]: no

[EX Q]: Question: Do high-oxygen-transmissibility soft contact lenses induce limbal hyperaemia?
Answer: SCL wear induces a marked increase in limbal hyperaemia during open-eye wear, which is not seen either in the no lens situation or when EHD lenses are worn. The pattern of limbal hyperaemia for both the open and closed eyes during EHD lens wear is very similar to that for the no-lens situation. The mechanism whereby SCL induces excess limbal hyperaemia has not been absolutely established, but it may involve local hypoxia.
[EX A]: no

[EX Q]: Question: Does hepatic steatosis in patients with chronic hepatitis C virus genotype 2 or 3 affect viral response in patients treated with peginterferon alpha-2a ( 40KD ) ( PEGASYS ) plus ribavirin ( COPEGUS ) for 16 or 24 weeks?
Answer: Steatosis did not influence the efficacy of treatment in our study population. Baseline viral load is a confounding factor, particularly in patients infected with genotype 3 and once baseline viral load was accounted for, the association between steatosis and SVR was not relevant.
[EX A]:
no
