Figure 4.

Influence of prolonged precentrifugation delay on selected eicosanoids in human serum. Boxplots visualize the variation of the concentration of selected eicosanoids in human serum of healthy volunteers after prolonged incubation for 0.5, 1, 2 and 4 h at room temperature (validation sample 1, n = 10) before centrifugation. Asterisks indicate differences between the time points as indicated by the respective brackets (* p < 0.05, *** p < 0.001). p-Values were calculated using linear mixed models or paired t-tests and were corrected for multiple testing using Bonferroni post-hoc test.
