  1. Prevalence of chronic rhinitis, nasal congestion and runny nose stratified according to risk factors: smoking, environmental tobacco smoke (ETS), occupational irritants, or their combinations among all responders and among responders with and without physician diagnosed allergic rhinitis. Probability figures are indicated below each prevalence figure. p-values are given between unexposed and those, who are exposed to one or more of the risk factors
