Age was represented in mean ± standard deviation. 46 patients were missing nasal polyp status, 12 missing smoking status, 15 missing allergic rhinitis status, 39 missing asthma, and 27 missing COPD. It should be noted that when patients made entries in both the spring—summer and in the fall—winter period they were included in both populations
