Nominally significant ( p < 0.05) associations between methylation levels and smoking were also observed at three of the four other selected smoking-associated CpG sites at baseline and 36 months after treatment, although only cg19859270 and cg03636183 are considered significant at a Bonferroni threshold for testing five CpGs ( p = 0.05/5 = 0.01; Table 2 ).
