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.

[Q]: Question: Does multidisciplinary care improve amputation-free survival in patients with chronic critical limb ischemia?
Answer: MDC pathways for the management of a population of CLI patients improved AFS by greater than twofold and should be the standard of care for the CLI population. Baseline nonambulatory status and unrevascularized patients also predict worse AFS. Wound healing remains prolonged regardless of preoperative or postoperative wound care. Future study is required to evaluate the costs and functional outcomes for MDC in the management of CLI.
[A]: yes


[Q]: Question: Is 14-3-3η a novel mediator associated with the pathogenesis of rheumatoid arthritis and joint damage?
Answer: Extracellular 14-3-3η activates key signalling cascades and induces factors associated with the pathogenesis of RA at concentrations found in patients with RA, and its expression is higher in patients with radiographic damage and RA progression.
[A]: yes


[Q]: Question: Are cerebrospinal fluid β-amyloid and tau associated with risk of delirium : a prospective cohort study in older adults with hip fracture?
Answer: Cognitive impairment predisposes to delirium, but in this study, postoperative delirium was not associated with baseline CSF Aβ1-42, tau, and Ptau levels. These findings suggest that CSF markers for plaque and tangle formation are not strongly associated with delirium risk in older adults with hip fracture.
[A]:
no
