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: Are standard equations accurate in assessing resting energy expenditure in patients with amyotrophic lateral sclerosis?
Answer: We found that standard equations used to calculate energy expenditure were not valid for patients with ALS. Moreover, the majority of our patients were either overfed or underfed. As underfeeding can cause diaphragm impairment, and overfeeding can increase ventilatory load, indirect calorimetry should be considered in ALS patients to determine optimal caloric requirement.
[EX A]: no

[EX Q]: Question: Does degenerative spondylolisthesis affect the outcome of unilateral laminotomy with bilateral decompression in patients with lumbar stenosis?
Answer: Our study thus indicates that preoperative degenerative spondylolisthesis does not worsen the outcome of patients with lumbar stenosis undergoing unilateral laminotomy with bilateral decompression. These results suggest that lumbar fusion is often unnecessary in patients with degenerative spondylolisthesis and lumbar stenosis if the posterior decompression technique is unilateral laminotomy with bilateral decompression.
[EX A]: no

[EX Q]: Question: Does the skin vasoconstrictor assay correlate significantly to airway or systemic responsiveness to inhaled budesonide in asthmatic patients?
Answer: It may not be possible to use the McKenzie vasoconstrictor assay to predict which patients are most or least susceptible to inhaled corticosteroids for anti-asthmatic efficacy or systemic adverse effects.
[EX A]:
no
