  1. Polygenic score (PGS) formulation is established based on TAG GWAS summary data using 1e-3 and 1e-4 p value threshold on nicotine dependence (ND) traits. The ND PGS was computed on COPDgene dataset (sample size = 4903), and tested for association with COPD case-control status, adjusted for smoking status (current smoker vs. non-smoker). #SNPs, the number of SNPs used in PGS computation, β, association coefficient (ie, log Odds Ratio).
