Total Polyp and SNOT-20 GAV score in patients suffering from chronic rhinosinusitis without nasal polyps (CRSsNP), chronic rhinosinusitis with nasal polyposis (CRSwNP), or chronic rhinosinusitis with nasal polyps and aspirin-exacerbated respiratory disease (AERD).

	Average Value ± Standard Deviation			p-Value of Pairwise Comparison
	CRSsNP	CRSwNP	AERD	CRSsNP-CRSwNP	CRSsNP-AERD	CRSwNP-AERD
Total polyp score	0 ± 0	3.40 ± 2.01	4.02 ± 2.89	<0.0001	<0.0001	0.3985
Total SNOT-20 GAV score	30.89 ± 19.92	36.32 ± 18.17	43.41 ± 19.23	0.5434	0.0488	0.1891
Total SNOT-20 GAV score if patients with TPS = 0 excluded	N/A	37.24 ± 18.01	49.14 ± 17.03		0.0028	0.0192

Total polyp score (TPS) and total Sino-Nasal Outcome Test-20 German Adapted Version (SNOT-20 GAV 20) scores (in all patients or selectively in patients with a TPS greater than 0) are shown in the respective patient groups. Significant differences between patient groups were observed, as follows: (One-way ANOVA TPS: p < 0.0001, total SNOT-20 GAV score p = 0.0443, total SNOT-20 GAV score if patients with TPS = 0 excluded: p = 0.0021). p-values of differences in pairwise comparisons using Tukey’s multiple comparison test are indicated. N/A = Not available. SD, Standard deviation. Bold indicated significant p-values.
