Estimated FEV1/FVC according to pack-years of smoking and rs8192575 The estimated FEV1/FVC ratio is generated by gene-by-smoking analysis using healthy individuals of KARE. Figure 6 implies that minor alleles G has negative impact in proportion to each increment of pack-years of smoking. The plot was generated by software R version 3.6.1 (R Foundation for Statistical Computing; Vienna, Austria).
