  1. *** p < 0.001, ** p < 0.01, * p < 0.05 obtained from Rao-Scott chi-square test of independence for categorical variables. Unknown or missing responses were excluded from analysis. Unweighted n may not add up to total N due to unknown or missing responses excluded from the analysis. Gastroesophageal reflux disease-like symptoms (GERS); acetylsalicylic acid exacerbated respiratory disease (AERD).
