Cox-proportional hazard analysis using age at onset of habitual smoking censored at non-habitual smokers.
1<p>Analysis was performed within family clusters using additive model. Age at interview in quartiles, gender, pc1, parental smoking and parental drinking were included as covariates.</p>2<p>Nominal P values are shown uncorrected for multiple testing. The Bonferroni-corrected significance threshold is P = 0.005.</p
Characteristics of study subjects who are daily smokers.
*<p>Indicates t test (two tailed) p = 0.0001.</p
Genotypes of rs1996371 significantly predict age at onset of habitual smoking.
<p>Genotypes of rs1996371 significantly predict age at onset of habitual smoking.</p
Distribution of age at onset of daily smokers with reference to alleles of rs1996371.
*<p>Indicates t test (two tailed) p = 0.0002.</p
Linkage disequilibrium between genotyped SNPs.
<p>Number in each square represents the a pairwise LD relationship (r<sup>2</sup>) between the two SNP's in Caucasians using HapMap data and varying red color represent the linkage disequilibrium values for that pair as measured by D′ (bright red shows high D′).</p
QTDT analysis with age at onset of daily smoking as quantitative variable.
1<p>Age at interview in quartiles, gender, first principal component of stratification (pc1), parental smoking and parental drinking were included as covariates.</p>2<p>Nominal P values are shown uncorrected for multiple testing. The Bonferroni-corrected significance threshold is P = 0.005.</p
