Plot showing interaction between ethnic group and smoking at AHRR cg05575921. Bars show mean DNA methylation levels in each group shown. Error bars represent standard deviations. Ethnic differences were observed between current smokers (t-test: n = 36, P = 2.0 × 10-3) but not between never smokers (t-test: n = 129, P = 0.44).
