CRSwNP subtype	Total patients (n)	Positive allergy history [n (%)]	Allergy testing performed [n (%)]	Positive allergy testing [n (%)]
CRSwNP NOS	132	74 (56.1%)	75 (56.8%)	66 (88%)
CCAD	41	40 (97.6%)	27 (65.9%)	25 (92.6%)
CRSwNP/CC	13	11 (84.6%)	5 (38.5%)	4 (80%)
AFRS	84	84 (100%)	70 (83.3%)	70 (100%)
AERD	86	71 (82.6%)	75 (87.2%)	58 (77.3%)

CRSwNP/CC = chronic rhinosinusitus with sinonasal polyps and central compartment involvement.

AERD = aspirin-exacerbated respiratory disease; AFRS = allergic fungal rhinosinusitis; CCAD = isolated central compartment atopic disease; CRSwNP NOS = chronic rhinosinusitis with nasal polyposis, not otherwise specified.
