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.
