Data are presented as n or n (%), unless otherwise stated. UAS: upper airway symptom; CRS: chronic rhinosinusitis. Patients with at least one positive culture were included. #: presence of persistent UASs or evidence of rhinitis or sinusitis on physical examination; ¶: patients without UASs and with a Lund–Mackay score ≤3; +: defined as UASs with evidence of sino-nasal involvement on sinus computed tomography (Lund–Mackay score ≥4).
