| Cough present (N = 28) | Cough absent (N = 27) | Total (N = 55)† | P-value* | |
|---|---|---|---|---|
| Sinus disease, N (%) | 10 (35.7) | 13 (48.1) | 23 (41.8) | .35 |
| Number of sinuses involved, median (IQR) | 1.5 (1-3) | 1 (1-3) | 1 (1-3) | .73 |
| NP thickening, N (%) | 16 (57.1) | 13 (50.0) | 29 (53.7) | .60 |
| Olfactory recess opacification, N (%) | 2 (7.4) | 2 (7.4) | 4 (7.4) | 1.00 |
| Mastoid opacification, N (%) | 2 (7.1) | 2 (7.4) | 4 (7.3) | 1.00 |
Abbreviations: IQR, interquartile range; NP, nasopharyngeal.
†
Due to missing data, for NP thickening, N = 54, and for olfactory recess opacification, N = 54.

For categorical variables, Fisher’s Exact test is used when expected cell counts <5, otherwise, the Chi-Square test is used. When median (interquartile range) is presented, the Mann–Whitney U test is used.
