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: Is the serum level of NX-DCP-R , but not DCP , increased in alcoholic liver disease without hepatocellular carcinoma?
Answer: NX-DCP-R, but not DCP, was not increased in alcoholics without HCC. As for negative screening for HCC, the specificity of the NX-DCP-R in alcoholics without HCC was better than that of DCP in alcoholics without HCC, and so could be a useful negative screening tool for HCC in millions of alcoholics worldwide.
no

Question: Is the absolute nucleated red blood cell ( aNRBC ) count at birth an indicator for retinopathy of prematurity ( ROP )?
Answer: We are unable to support the previously reported relationship of aNRBCs with ROP. Our population was three times larger, had higher aNRBCs and less retinopathy than previously reported. A biological principle of cause and effect or predisposition to ROP as reflected by aNRBCs should have been easier for us to demonstrate, if it existed.
no

Question: Does neuronal nitric oxide synthase contribute to the modulation of pulmonary vascular tone in fetal lambs with congenital diaphragmatic hernia ( nNOS in CDH lambs )?
Answer: We conclude that nNOS protein is present in the lungs and pulmonary artery of near full-term lamb fetuses with diaphragmatic hernia, but that it does not contribute to the reduction of pulmonary vascular tone at birth.

no
