Data are presented as n, n (%), mean±sd or median (interquartile range), unless otherwise stated. FEV1: forced expiratory volume in 1 s; CT: computed tomography. #: defined as UASs with evidence of sino-nasal involvement on sinus CT (Lund–Mackay score ≥4); ¶: patients without UASs and with a Lund–Mackay score ≤3. p<0.05 was considered significant.
