Arachidonic Acid Level After 2 Weeks of Treatment
大体时间：2 weeks
|
Arachidonic acid level (20:4n6) in the cholesterol ester lipid class. The mean reported was an adjusted mean, which was obtained from running a 2-period crossover model that had fixed treatment and period terms and a random participant term. |

Fasting Blood Lipidomic Levels After 2 Weeks of Treatment
大体时间：2 weeks
|
Change in fasting blood cholesterol ester, lysophosphatidylcholine, phosphatidylcholine, phosphatidylethanolamine, and triacylglycerol levels compared to placebo. The mean reported was an adjusted mean. |
2 weeks

Serum Proprotein Convertase Subtilisin-like/Kexin Type 9 (PCSK9) Level
大体时间：2 weeks
|
Two days of standardized, pre-packaged meals were provided prior to the 10-hour fast required before blood collection. To assess how consumption of a meal would affect levels of plasma PCSK9, following each of the fasting blood draws, participants were asked to consume a high fat meal (heavy whipping cream + vanilla ice cream in a 1:4 ratio [dose = 162 g/m^2]) within 20 minutes. For the duration of the test, participants were to remain seated or recumbent until blood samples were drawn 4 h after meal completion. The mean reported was an adjusted mean (defined in first outcome measure). |

Blood Linoleic Acid Levels
大体时间：2 weeks

Change in Fasting Delta 5 Desaturase Enzyme Activity Compared to Placebo
大体时间：2 weeks
|
Change in fasting delta 5 desaturase enzyme activity compared to placebo.
Delta 5 desaturase enzyme activity is defined as the ratios of C20:4n-6 to C20:3n-6 and C20:5n-3 to C20:4n-3.
