  1. a Adjusted effect estimates (for sex, age, atopy, and smoking) are presented as odds ratios (OR) and 95% confidence intervals. Statistically significant results are presented in bold.
  2. bAll results that reached statistical significance with respect to genotype-associated risk in either exposure-strata, or in the analysis of interaction between genotype and exposure status, are presented.
  3. cAnalysis of interaction between exposure and genotype was performed in a separate model using logistic regression with interaction term. P-values regarding interaction between exposure and genotype are indicated by P*.
