Genotype, allele, and haplotype frequencies of the β₂-adrenergic receptor gene (ADRB2)

^*Each OR (95% CI) was calculated using the co-dominant, dominant, and recessive models. Logistic regression analysis was used to control age and sex as covariates. Haplotypes with a frequency >1% are listed.

TDI-OA, toluene diisocyanate-induced asthma patients; AEC, asymptomatic exposed controls; NC, unexposed normal controls; n, number of subjects; OR, odds ratio; 95% CI, 95% confidence interval; NA, not available.
