Primary outcome measure of this trial was the improvement of FEV1 after
the intervention with Hypertonic Saline nebulization prior to chest
physiotherapy. The mean FEV 1 improvement of children receiving HS was
higher than those receiving conventional therapy, where the difference
was statistically significant at both phases of the study as shown in
table 2 and figure 2.
