From: Phospholipids in lipoproteins: compositional differences across VLDL, LDL, and HDL in pregnant women
Plot of the ratios between the metabolite medians and sum of all mono-unsaturated sphingomyelins (SM) as well as poly-unsaturated ester-linked phosphatidylcholines (PCaa) and ether-linked phosphatidylcholines (PCae) in the different lipoprotein species. The 95% confidence intervals for the ratios are estimated by bootstrapping and significance level calculated by Wilcoxon Mann Whitney U-Test. The definition of the stars is the following: ‘*’ P < 0.05, ‘**‘P < 0.01, ‘***’ P < 0.001 . Only metabolites that are significantly different in at least one comparison are included. HDL, high density lipoprotein; LDL, low density lipoprotein; VLDL, very low density lipoprotein
