Multiple regression analysis of C242T genotypes.

<p>HDL = high density lipoprotein.</p><p>LogTG = Log transformation of the triglycerides.</p>*<p>Adjusted for sex, age, body height, body weight, antihypertensive medication, antidiabetic medication, current smoking, alcohol intake and heart rate.</p>#<p>Adjusted for sex, age, body height, body weight, antihypertensive medication, antidiabetic medication, alcohol intake and heart rate.</p

Characteristics of the study groups stratified by genotype among smokers and nonsmokers.

<p>HDL = high-density lipoprotein; LDL = low-density lipoprotein.</p>*<p>The values are the median (interquartile range).</p

Difference of prevalence of metabolic syndrome between C242T genotypes in all participants and smokers.

<p>The odds of prevalence of metabolic syndrome in genotypic group is expressed relative to the overall risk of all participants (A) or smokers (B), and adjusted for age, sex, body height, body weight, antihypertensive medication, antidiabetic medication, current smoking, alcohol intake and heart rate. Vertical lines denote 95% confidence intervals. For each genotype, the number of participants is given.</p

Difference of prevalence of metabolic syndrome between C242T genotypes in different smoking dose groups.

<p>The odds of prevalence of metabolic syndrome in genotypic group is expressed relative to the participants in each smoking dose group, and adjusted for the same covariates as in the <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0031926#pone-0031926-g001" target="_blank">Figure 1</a>.</p
