Statistical analysis:
The data were analyzed using IBM SPSS version 20.0 software. Categorical
variables were expressed using frequency and percentage and numericals
using mean and standard deviation. An independent sample t-test was used
to test the statistical significance of comparing mean change from
baseline of SNOT- 20, Serum IgE, and AEC at one month between two
groups. A Chi-square test with continuity correction was used to test
the statistical significance of the association of all categorical
variables (Predominant symptoms, histopathological findings, and nasal
endoscopic grading) between both the groups. P-value < 0.05
was considered to be statistically significant.
