  1. Patient characteristics and results of specimens taken from the nasal cavity. Control = mucosa from inferior turbinate from patient without inflammation of nasal mucosa and without sinonasal disease, P value1 = by pair-wise comparison between winter and spring by Wilcoxon test; P value2 = comparison between control and atopy groups either in winter (w) or in spring (s) by *Fisher's exact test (discrete) or Kruskal Wallis test (continuous).
