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: Does transcriptome analysis of proton pump inhibitor-responsive esophageal eosinophilia reveal proton pump inhibitor-reversible allergic inflammation?
Answer: These findings provide definitive evidence that PPI-REE is a disease entity with significant molecular overlap with EoE, suggesting that many patients with PPI-REE represent a continuum of the same pathogenic allergic mechanisms that underlie EoE and thus might constitute a subphenotype of patients with EoE. The ability of PPI therapy to nearly entirely reverse gene expression associated with PPI-REE, particularly that associated with classic features of allergic inflammation, provides new insight into potential disease etiology and management strategies for patients with significant esophageal eosinophilia.
[EX A]: yes

[EX Q]: Question: Is tobacco smoking associated with decreased semen quality?
Answer: Results demonstrated a decline in semen quality in a dose dependent tobacco smoking manner.
[EX A]: yes

[EX Q]: Question: Is β-blocker therapy associated with adverse outcomes in patients with pulmonary arterial hypertension : a propensity score analysis?
Answer: There was no statistically significant difference in long-term mortality between propensity score-matched pairs of PAH patients with and without β-blocker use. These findings need further validation in prospective clinical trials.
[EX A]:
no
