Values are the mean (standard deviation), percentages, or median (interquartile range). The proportions of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) or arachidonic acid (AA) in total free fatty acid were defined as EPA (%), DHA (%) and AA (%), respectively. HDL, high‐density lipoprotein; HOMA‐IR, homeostasis model assessment of insulin resistance; LDL, low‐density lipoprotein.
