Box plots showing median and interquartile range for mucociliary clearance at 60 min on the placebo and HS visits for all children and for subgroups of children with less than or greater than the median MCC60 after placebo. The "whiskers" represent the 10th and 90th percentiles. Open circles represent data outside the 10th and 90th percentiles. The change in MCC with HS was not significantly different from placebo for all children, or for the subgroup comparison.
