Input: Consider Input: Question: Do traditional clinical risk assessment tools accurately predict coronary atherosclerotic plaque burden : a CT angiography study?
Answer: Coronary risk stratification using a risk factor only-based scheme is a weak discriminator of the overall atherosclerotic plaque burden in individual patients. Patients with little or no plaque might be subjected to lifelong drug therapy, whereas many others with substantial plaque might be undertreated or not treated at all.

Output: no


Input: Consider Input: Question: Does the ets-domain transcription factor Spdef promote maturation of goblet and paneth cells in the intestinal epithelium?
Answer: Spdef acts downstream of Math1 to promote terminal differentiation of a secretory progenitor pool into Paneth and goblet cells.

Output: yes


Input: Consider Input: Question: Is osteoprotegerin a Better Serum Biomarker of Coronary Artery Calcification than Osteocalcin in Type 2 Diabetes?
Answer: Our results suggest that OPG is a more useful serum biomarker than OC or ucOC for identifying those at increased risk of arterial calcification in type 2 diabetes.


Output: yes
