Example 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.
Example Output: no
