From: An interaction between Nrf2 polymorphisms and smoking status affects annual decline in FEV1: a longitudinal retrospective cohort study

Figure 3

Effect of interaction between rs6726395 SNP and cigarette smoking status on annual decline in FEV 1 . Data are presented as mean (95% CI). Light gray bar and striped bar represent rs6726395 G/G + G/A and A/A genotype groups, respectively. Only in ex- and current-smokers was the annual FEV1 decline significantly different between the 2 groups. The interaction effect was analyzed by general linear models adjusted for sex, age, BMI, FEV1/FVC ratio, serum IgE levels, and affection of bronchial asthma.
