Example Input: Question: Do inhaled corticosteroids affect behaviour?
Answer: There is a difference in behaviour between healthy children and asthmatic children on ICS, but not when compared with children visiting the ENT department. Although hyperactivity, aggressiveness and anxiety might occur in children on ICS, this is probably caused by individual susceptibility. Being under specialist care can possibly explain behavioural differences between children on ICS and healthy controls.
Example Output:
no
