Ex Input:
Question: Does chronic reduction of myocardial ischemia attenuate coronary collateral development in miniswine?
Answer: We conclude that growth and development of the coronary collateral circulation measured functionally during exercise at 90% of maximal heart rate is unrelated to the extent and duration of myocardial ischemia in this model.

Ex Output:
no


Ex Input:
Question: Does exacerbation of headache during dihydroergotamine for chronic migraine alter outcome?
Answer: After controlling for nausea and other factors, headache exacerbation with DHE infusions is not an independent predictor of poor headache outcome and clinicians should not interpret its presence as a reason to stop treatment. The focus of management should be on controlling nausea as it is the most important modifiable factor in achieving a good headache outcome with an inpatient course of IV DHE for chronic migraine.

Ex Output:
no


Ex Input:
Question: Does serum free light chain response after 2 courses of induction chemotherapy predict prognosis in myeloma patients?
Answer: Early response assessment in terms of sFLC after 2 courses of induction CT seems to have a prognostic effect in MM patients. The methodology and timing of the evaluation based on sFLCs needs to be validated in prospective studies.

Ex Output:

yes
