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: Are anticytomegalovirus antibody titres associated with caregiving burden in younger caregivers?
Answer: These data suggest that in the absence of immunosenescence, the chronic stress of caregiving is not sufficient to compromise the immune response to persistent CMV infection. However, an indirect mechanism to poorer health in caregivers might be via adoption of disadvantageous health behaviours in response to stress. Statement of contribution What is already known on this subject? Older caregivers of spouses with dementia show a poorer immune response against latent viruses when compared to age- and sex-matched controls. Younger parental caregivers of children with developmental disabilities show a poorer antibody response to vaccination. What does this study add? The study showed no association between caregiving stress and CMV antibody titre in young caregivers. There were higher CMV antibody titres in the caregivers who engage in unhealthy behaviours.
no

Question: Does slower infusion of metoclopramide decrease the rate of akathisia?
Answer: Slower infusion of metoclopramide reduces the incidence of akathisia.
yes

Question: Is hepatic encephalopathy associated with slowed and delayed stimulus-associated somatosensory alpha activity?
Answer: The present results provide the first evidence for a slowing of oscillatory activity in the somatosensory system in HE in combination with a previously unknown deficit of S1 in adjusting activation levels back to baseline.

yes
