Association between genotypes and smoking-rrelated phenotypes.

Abbreviations: CPD, mean number of cigarettes smoked in one day; FTND, Fagerstrom Test Nicotine dependence test; M. major allele; m. minor allele; NS. non-significant (P>0.05); PYS, mean pack years smoked (see text for explanations). For each polymorphim, between-genotype comparisons were corrected for multiple comparisons using the Bonferroni method, where the threshold P-value is obtained by dividing 0.05 by the number of comparisons, i.e. n = 3, corresponding to each genotype (thus, threshold P-value = 0.017). P-values that were below the threshold P-value are shown in bold.Data are shown as mean±SD values.
