Example Output: no

Example Input: Question: Does novel individual metabolic profile characterize the protein kinase B-alpha ( pkb-/- ) in vivo model?
Answer: Specific metabolic characterization should be assessed individually. Therefore, our in silico model enables novel insights inaugurating specific primary preventive strategies targeting individual metabolic profiling precisely.
Example Output: yes

Example Input: Question: Does the preoperative neutrophil/lymphocyte ratio correlate with the 21-gene recurrence score in estrogen receptor-positive breast cancer patients?
Answer: Our data suggest that the preoperative NLR does not predict the 21-gene RS in patients with early-stage hormone-sensitive BC.
Example Output:
no
