Figure 3

Box plots showing median and interquartile range for mucociliary clearance at 90 min on the placebo and HS visits for all children and for children with less than or greater than the median MCC90 after placebo. The "whiskers" represent the 10^th and 90^th percentiles. Open circles represent data outside the 10^th and 90th percentiles. The change in MCC with HS was not significantly different from placebo for all children, but was significantly different for the comparison of the subgroups (p = 0.045).
