Values are expressed as mean (SD) or median (25th and 75th centile) for continuous variables and % for categorical variables.
Total LCn3PUFAs were defined as the sum of eicosapentaenoic, docosapentaenoic, and docosahexaenoic acids. Fatty acids were expressed as a percentage of total serum fatty acids.
DHA, docosahexaenoic acid; EPA, eicosapentaenoic acid; HDL-C, high density lipoprotein cholesterol; LCn3PUFA, long chain n-3 polyunsaturated fatty acid; LDL-C, low density lipoprotein cholesterol.
