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 gender difference affect the outcomes of eccentric rotational acetabular osteotomy used in hip dysplasia?
Answer: The mean operative time and the blood loss were not significantly different between male and female patients. Postoperative CE angle tended to be smaller in male than female patients. The survival rate was not significantly different between males and females. Gender difference did not affect the clinical outcomes of ERAO in patients with hip dysplasia.
no

Question: Does pharmacological preconditioning using intraportal infusion of L-arginine protect against hepatic ischemia reperfusion injury?
Answer: Pharmacological preconditioning with intraportal L-arginine provided protection against hepatic I/RI in early phases of the reperfusion period. The mechanisms underlying the protective effect may include preservation of the mitochondrial structure and inhibition of caspase-3 activity.
yes

Question: Does hypothermia alter somatosensory evoked potential amplitude and global cerebral oxygen extraction during marked sodium nitroprusside-induced arterial hypotension?
Answer: Thus, hypothermia to 32 degrees C does not alter MN-SSEP amplitude and global cerebral oxygen extraction during marked sodium nitroprusside-induced arterial hypotension with a mean arterial pressure of 40 mmHg but prolongs MN-SSEP latencies during propofol-remifentanil anesthesia in individuals without cerebrovascular disease.
no
