Improvements are presented as mean ± SD with a 95% Confidence Interval. HS,Hypertonicsaline; ACT, Airway Clearance Technique;FEV1,Forced Expiratory Volume in one second;FVC, Forced Vital Capacity;

FIGURE 2 Improvement in FEV1 during First and Second phases

FIGURE 3 shows the higher mean improvement in FVC in HS Arm of children at both phases of the study where the difference is statistically significant.

FIGURE 3 Improvement in FVC during First and Second phases

Number of exacerbations each child experienced was recorded during both phases and shown in Table 2.There was a significant difference between the two groups in the mean number of exacerbations during phase I where the lesser number of exacerbations were seen in the HS group. However no significant difference in the number of exacerbations was seen during phase II of the study in the two groups of children.
