Abbreviations: FEV1, forced expiratory volume in 1 s; SNP, single nucleotide polymorphism; Chr, chromosome; MAF, minor allele frequency; β, regression coefficient; mGST3, microsomal glutathione S-transferase 3; SOD3, superoxide dismutase 3; GSR, glutathione reductase; GSTA4, glutathione S-transferase A4.
Data shown for associations with P < 0.005 for the SNP single-marker effect on rate of change in FEV1, sorted by race/ethnicity, chromosome and base pair position. Statistically significant associations satisfying the Bonferroni-adjusted threshold (African Americans: P < 2.3 × 10−4; European Americans: P < 3.0 × 10−4) are bolded.
Regression coefficient and standard error for the SNP × time product term in the corresponding mixed effects model.
Genetic model is defined in reference to the minor allele for each SNP.
