Interaction between sample tissue type and smoking status in HBD gene expression. a, d Boxplots comparing HBD gene expression between two groups dichotomized on a single clinical variable: tissue type (a) or smoking status (d). b, c, e, f Boxplots comparing HBD gene expression between two groups defined by a combination of two clinical variables: different tissues in smoker (b), different tissues in non-smoker (c), tumor from patients with different smoking status (e), and normal tissues from patients with different smoking status (f)
