There are limitations to our study. First, infants in the control group did not receive a placebo treatment. However, there was no difference in total lipid intake between the active and the control group. Second, when investigating the impact of parenteral lipids on infant LCPUFA levels we did not account for other potential confounders such as blood transfusions, LCPUFAs in human milk, LCPUFAs in the human milk fortifiers, and lipids present in other fortifiers, which may impact infant plasma levels [
