Characteristics of subjects by ethnicity.

<p>Values presented are means ± SD. Subcutaneous and visceral adipose tissue were not normally distributed and were transformed using the natural log for statistical analyses; values presented are the median (25^th percentile, 75^th percentile). Significant differences between ethnic groups were assessed by ANOVA. Ethnic-specific differences in season of blood collection were assessed by Pearson's chi-squared test.
