Association between genotypes and smoking-rrelated phenotypes.

<p>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 <i>P</i>-value is obtained by dividing 0.05 by the number of comparisons, i.e. n = 3, corresponding to each genotype (thus, threshold <i>P</i>-value = 0.017). <i>P-</i>values that were below the threshold <i>P</i>-value are shown in bold.</p><p>Data are shown as mean±SD values.
