Anthropometric, biochemical characteristics and lipoprotein subfractions in obese patients according to different degrees of insulin resistance.

Data are expressed as mean ± standard deviation for parametric data or as median (25th and 75th percentiles) for non-parametric data. Values with different superscripts (a,b,c) indicate that the differences among groups are significant (p<0.05) when compared by means of one-way ANOVA or Kruskal-Wallis for data with normal or without normal distribution, respectively, followed by a post hoc test.
Abbreviations: MetS, metabolic syndrome; BMI, body mass index, RBP4, retinol binding protein-4; VLDL: very low-density lipoprotein; IDL: intermediate-density lipoprotein; LDL: low-density lipoprotein; HDL: high-density lipoprotein.
