Distribution of relative apelin gene expression in visceral and subcutaneous adipose tissues according to the tertile of energy-adjusted dietary glycemic index (GI). Results are expressed as mean ± SEM. P-values for the association of apelin gene expression in the lowest tertile in comparison with medium and highest tertile of energy adjusted dietary GI in visceral adipose tissue were 0.928 and < 0.001, respectively. p-values for the association of apelin gene expression in the lowest tertile in comparison with the medium and highest tertile of energy-adjusted dietary GI in subcutaneous adipose tissue were 0.878 and < 0.001, respectively
