  1. Regression analysis was used to investigate the association between LTB4R SNPs and baseline percent predicted FEV1 in the Adult Asthma Cohort (n=299) using the additive model. 0, 1, 2 represent number of genotypes for major, heterozygotes and minor genotypes respectively. *Dominant model analysis was completed for rs2332320 due to low number of minor allele homozygotes in the additive model.
