Task: Answer Verification
Input (English): Question: Does acute inhalation of hypertonic saline improve mucociliary clearance in all children with cystic fibrosis?
Answer: These data suggest that percent MCC varies significantly between children with CF lung disease and normal pulmonary functions, with some children demonstrating MCC values within the normal range and others showing MCC values that are below normal values. In addition, although MCC did not improve in all children after inhalation of HS, improvement did occur in children with relatively low MCC values after placebo. This finding suggests that acute inhalation of hypertonic saline may benefit a subset of children with low MCC values.
Output (English): no
