Fig. 4From: Lipoprotein turnover and possible remnant accumulation in preeclampsia: insights from the Freiburg Preeclampsia H.E.L.P.-apheresis studyLipoprotein profile before and after apheresis. Lipoproteins pre and post apheresis were separated into their density classes and LDL were divided into 6 subclasses by further ultracentrifugation. Density increases from left to right (see methods for details). a: Measured ApoB values (mean ± SD of 6 patients) are given as closed symbols (measured pre-apheresis values: closed triangles; measured post-apheresis levels: closed squares). Expected post apheresis values calculated by apheresis efficiency are given in open red circles. b: Comparison of measured and calculated post-apheresis levels by Wilcoxon matched pairs test, a value of p < 0.05 was considered statistically significantBack to article page
