Data are mean ± SD
Methylation cohort represents a subcohort of the gene expression cohort; no statistical significance for phenotype data between the gene expression and methylation cohorts was found
BMI body mass index = weight (kg)/height (m)²
^aSignificant difference (p < 0.05) between lean and obese groups
